George Westinghouse

The Westinghausen family tree stretches back to that of the ninth century in Westphalia, Germany. Some of the family decided to emigrate to Europe and later settle in the United States. In the nineteenth century, George Westinghouse decided to move all over the former United States and settled in Central Bridge, New York where he had George Westinghouse II. Born into a family of ten (which would become twelve later on) on October 16, 1846, George Westinghouse Jr. (son of George Westinghouse and Emmeline Vedder) was born into an agricultural family. George Jr.’s father moved the family to Schenectady to sell farming tools. After serving the Union Army for three years at the age of fifteen, George II (later to…

Introduction to the Sciences

The statement that; “Computers are part of our everyday lives.” Is so correct, I don’t think the people of today would know how to do anything without the computer. Between the desktop top computers and laptops to the smart phone everything can be stored using less space and the ability to locate stuff so much more easier that if the world of today lost computers around the world for even just an hour would put this world in an uproar. There are three essential properties of every material that scientists use as a premise for almost every study. The kind of atoms is the first one that the material is made up of. You will have your neutral elements and…

Circuit Lab Report

Ohm’s Law is V = I * R or in some cases I = V / R. The next two laws were established by a German physicist by the name of Gustav Kirchhoff. Kirchhoff’s first law is his voltage law. Kirchhoff’s Voltage Law (KVL) states that around any loop in a circuit, the voltage rises must equal the voltage drops. The next law that Kirchhoff introduced was his current law. Kirchhoff’s Current Law (KCL) states that the total current entering a junction must equal the total current leaving the junction. These laws, however, cannot be proven or tested without the aid of a multimeter. A multimeter is an instrument designed to measure electric current, voltage, and usually resistance, typically over…

Black Magic

KVS Krishnamohan** The world’s worst power outage affected 600 million people, business worth an estimated $1.5 billion was lost, trains stopped, flight schedules were thrown out of gear, and miners were trapped, in deep coal shafts and hospitals had to switch the emergency operators. That’s half of the population in the darkness on 31st July 2012. This is because of the failures of three grids in supplying to north, eastern, north eastern regions of the country. In recent times power outrages made headlines in US, Canada, Brazil and Greece. This is not exception to India, but this crisis in not an ordinary crisis, because investors are looking infrastructure support from the government of India. Repeated grid failures may create a…

Smart Grid

The current electricity infrastructure in the Unites States consists of one way “communication” between the electric company and the homes receiving the electricity with the communication coming from the electric company to the homes. The current electricity infrastructure in the United States is more than 100 years old and because of this fact, it is outdated resulting in a great lack of efficiency. There is no way for the electricity company to obtain information from the individual homes pertaining to actual usage. Smart grids allows for two way communications between the electricity company and the homes allowing both electric companies and homes to operate more efficiently. This two way communication will allow home users to cut costs by efficiently utilizing…

Electric Generator

Early 20th century alternator made inBudapest, Hungary, in the power generating hall of a hydroelectric station In electricity generation, an electric generator is a device that converts mechanical energy to electrical energy. A generator forces electric charge (usually carried by electrons) to flow through an external electrical circuit. The source of mechanical energy may be a reciprocating or turbine steam engine, water falling through a turbine or waterwheel, aninternal combustion engine, a wind turbine, a hand crank, compressed air, or any other source of mechanical energy. Generators supply almost all of the power for the electric power grids which provide most of the world’s electric power. The reverse conversion of electrical energy into mechanical energy is done by an electric…

Self Reliance Written by Emerson Translation of Tamil

A UPQC has the same structure as a UPFC. It can inject current in shunt and voltage in series simultaneously in a dual control mode. Therefore it can perform both the functions of load compensation and voltage control at the same time. The UPQC must also inject unbalanced and distorted voltages and currents and hence its operating characteristics are than that of a UPFC. Furthermore their operation philosophy is different. The UPQC is also an (PQ) enhancement device. UPFC and can operate under non-balanced conditions, whereas the UPFC is assumed to operate under balanced sinusoidal conditions. Source: A. Ghosh, G. Ledwich – Power Qualtiy Enhancement using custom power devices (found at google: E-books) Quality of power supply has become an…

Voltmeter and Ammeter

Measuring Voltage Measuring the voltage between two points of an electrical current can be done with an instrument called a voltmeter. One type of voltmeter is a direct-current voltmeter. When taking a voltage reading the instrument is placed across the portion of the circuit that is to be measured. Direct-Current Voltmeter The direct-current voltmeter has a horseshoe shaped magnet, with a semicircular piece of soft iron attached to each end of the magnet. The iron is also magnetized. The iron ends of the magnet serve to direct the magnetic field in the direction of a small iron cylinder that is positioned between the ends (or poles) of the magnet. Taking advantage of the soft iron’s characteristic to become highly magnetized,…

Saturable Reactor

Saturable reactor or magnetic amplifier is a circuit that used to control very large load of AC with very small input DC. The saturable reactor consists of three essential elements : Direct current source, magnetic core with windings, and alternating current source. How it work? The AC load circuit run on to magnetic core and the DC control circuit is also went on to the same core. Ac current flows through winding and Since this current is alternating, the flux set up in the magnetic circuit loop is constantly changing in magnitude and direction. This means the field builds up to a maximum in one direction, collapses, and builds up to a maximum in the opposite direction DC circuit will…

A Description of Alternating Current

Abstract Alternating current (AC) electricity is the type of electricity that commonly used in houses and businesses throughout the world. While direct current (DC) electricity is flowing in one direction through a wire, the direction of the AC is moving in a back-and-forth motion. AC electricity is created by an AC electric generator, which is determining the frequency. The special about AC electricity is the voltage can be readily changed, so that will make it more suitable for long-distance transmission than DC electricity. However, AC can employ capacitors and inductors in electronic circuitry that will allow for a wide range of applications. This experiment was amid to create signals for AC voltage using function generator, measuring the signals using oscilloscope,…

The Importance of Electricity

As long as the electricity is available, no one thinks much about it. The importance is realized when the power goes out. Whether it’s during the day or at night, electricity keeps our lives in order. It affects your business, your schedule and even your entertainment. Electricity runs everything in our everyday life. Gas stations can’t pump gas without it. Businesses have to close because their cash registers won’t work without it. Restaurants can’t cook food without it. Our lives almost come to a standstill without electricity. These are the times when back up electricity is most needed and becomes very important. It can keep our clocks running, so we aren’t late for work. We can have breakfast before we…

Cross-Cultural Competency

You have no choice about which culture programs you from birth. So don’t judge others because of their cultural differences from you. All complex societies (such as our own) contain subcultures that share the larger cultural outlook, but have significant differences. The culturally savvy Soldier will take an active interest in any culture he or she works in. ReALLIT: read, ask, look, listen, investigate, and think. Look for styles of interaction/proper behavior, greeting rituals, local dress, daily routines and movements, transportation, eating habits, treatment of children, major or common ceremonies and rituals, and frequencies of young men visible on the street. Soldiers who are not culturally savvy compromise the mission by alienating the locals, or even by creating major crises….

History of Electricity

Electricity is one of the greatest discoveries of man, this is simply because it brings light and it has open door to so many other discoveries and invention. Men of today actually depend on this form of energy to live and perform his or her basic duties. Machine of today depend mostly on electricity to function properly. Magnetism, which is an aspect of electromagnetism, is considered one of the fundamental forces of nature (Blume, 2007). Those forces are usually produced by the movements of the charges and this has greatly show the influence of electricity on magnetism or vice versa (that is there is a close relationship between the electricity and the magnetism). Since the forces that hold molecules are…

The positive charges have made the puck bounce back off, while the negative charges have made the puck oscillate to each there meaning that the puck and negative charges are compatible and moves towards each other. However, the two charges and the electric field had played a significant role by letting the audience figure out…

Circuits Experiment

1. Describe the type of meter movement used in analog meters. The current in the circuit is used in basic meters to measure the voltage drop or current in the circuit. The current passes through the coils of wires, which is then magnetized. Inside the apparatus, there is also a permanent magnet which opposes the magnetic field of the magnetized coil of wire that is connected to the pointer therefore, as we see in meters, the pointer moves. There is also a spring connected to the pointer to counteract the torque produced by the pointer, so the pointer will move in proportionality with the current density. As the current increases, the pointer will travel farther. When the current is interrupted,…

The Potential of Malunggay Leaf Extract

Electrical phenomena have been studied since antiquity, though progress in theoretical understanding remained slow until the seventeenth and eighteenth centuries. Even then, practical applications for electricity were few, and it would not be until the late nineteenth century that engineers were able to put it to industrial and residential use (Jones, 1991). The foundation of modern electrical science was definitely established in the Elizabethan Age (http://inventors.about.com/cs/inventorsalphabet/a/electricity.htm). Scientists often depict it as the golden age in English history. During this age, the start of the advance in electricity was made possible by William Gilbert. His book entitled “Magneticisique Corporibus” (On the Magnet), influenced and inspired inventors and scientists and was passed from generation to generation. Today, electricity is an essential part…

Critical Essay on Electricity Deregulation

Electricity deregulation in the US state of Texas was the outcome of the Texas Senate Bill which was approved on January 1, 2002 which was the result of the infamous California electricity crisis of 2000 and 2001. During the crisis the different areas of California suffered black outs which were artificially created by a few companies and exploited them by supplying electricity at premium prices. The deregulation meant the most of the consumers of electricity could now choose their power supplier from a number of retail electric providers (REPS) which are private companies rather than owned by the municipality or the government. The Public Utility Commission of Texas will have no control on the amount that will be charged from…

The Burdon of Transportation

With so many new drivers hitting the roads every year, it becomes increasingly more important to consider our environment and the impacts we make. Air pollution in the United States comes from many types of engines, industries, and commercial operations. Pollution sources that move are known as “mobile sources.” These sources include vehicles, engines, and motorized equipment that produce exhaust and evaporative emissions (Office of Transportation and Air Quality, 2012). The major concern about air pollution is global warming. This is when gases like carbon dioxide, found in vehicle exhaust, get trapped in the atmosphere and cause our planet to retain more heat from the Sun than normal. Global warming endangers our health, jeopardizes our national security, and threatens other…

Unknown Girl and Electricity Comes to Cocoa Bottom

Compare and contrast the presentation of the poets’ attitudes to progress in Unknown Girl and Electricity Comes to Cocoa Bottom. People have been thinking about what ‘progress’ means for hundreds of years. We normally associate it with positive impacts and things changing for the better, which the majority of the time is correct. Edward E Cummings once said ‘Nothing recedes like progress.’ and in the poems ‘Unknown Girl’ and ‘Electricity Comes to Cocoa Bottom’ the poets agree with this statement. Alvi and Douglas present a negative view to the force of progress, we begin to question our understanding of progress, the benefits we gain from it and the danger that we lose what is most important when blindlessly pursuing it….

How batteries can change the way we live?

Battery is a device, which consists of one or more electrochemical cells, which converts stored chemical energy into electrical energy. Batteries are used everywhere in our daily life. We use them in technology, like mobile phones, computers, music players and etc. We use them for medical reasons, like wheelchairs, defibrillator, pace makers, hearing aids and many others. Batteries have solver an enormous amount of problems. For instance, without batteries there wouldn’t be mobile phones and computers. Batteries work by reduction and oxidation reaction. Battery is a device, which consists of one or more cells. Each cell consists of at least two half-cells: a reduction cell and an oxidation cell. Chemical reactions in the two half-cells provide the energy for the…

Energy Planning Proposal

In this time energy is one of the most sought after resources we ask for. It powers just about everything we deal with and use on a daily basis. From the ATM to the charger for your phone. This energy costs money yet should we just throw the money towards the simplest solution at the time, or would it be wiser to look towards the long term use of the method of making energy? Renewable energy while it’s most negative aspect is the costly measures of setting it up has possibly one of the best three aspects about it. One it emits little to no greenhouse gases. Second it is an energy source that renews itself so it has little…

The ‘War of Currents’

The competition between George Westinghouse and Thomas Edison to supply electricity to cities in the late 1880s is often called the ‘War of Currents’, as this battle ultimately decided which type of current became the standard for the generation of electricity today. Due to different advantages and disadvantages, Edison promoted direct current (DC) for electric power distribution, whereas Westinghouse and Nikola Tesla both advocated alternating current (AC). Edison’s direct current was initially the standard for the United States for electricity distribution as not only did DC work well with incandescent lamps (the principal load of the day), but DC systems could be directly used with storage batteries, providing valuable load-levelling and backup power during interruptions of generator operation. Also, Direct…

Science Report on Electromagnetism

This report will be done on the theory of Electromagnetism. Electromagnetism is the force that combines electricity and magnetism. Electromagnetism is found in everyday things that shape our lives. It is the cleanest force used to make energy today, and it is used in almost every home appliance that is in a standard middle classed home. The E-M force is the most commonly under looked force that helps us live. Without Electromagnetism, we would be falling through floors, literally! E-M force can be found even in military weapons, and even the radio uses electromagnetism. Electromagnetism can save lives when used in critical medical equipment. This is one truly amazing force that we can no longer overlook if we wish to…

Planning & Designing Experiment: Investigating the current

Title: Investigating the current – potential difference relationship for a metal wire. Aim: To design an experiment that will facilitate an I – V Graph to be ascertained of a metal wire and thus find the resistance of the wire by deriving the inverse of the gradient of the graph. Skill: Planning & Designing Theory: Resistance is a property of any object or substance to resist or oppose the flow of an electrical current. The quantity of resistance in an electric circuit determines the amount of current flowing in the circuit for any given voltage applied to the circuit. This is according to Ohm’s law. The unit of resistance is the Ohm which has the Greek letter ‘Omega (Ω)’. By…

Resistors in series and parallel

Resistors are used in various real life applications to perform tasks that involve: limiting the current that goes through a section of a circuit, introducing a voltage drop in a circuit, generating heat and the protection of components of a circuit. It is important to calculate the resistance of resistors so that the electrical circuits produced using them will perform in the manner that their manufacturer wanted them to. If the wrong resistance/resistor is used then delicate components that need only a relatively small amount of current may be destroyed. All resistors have a level of tolerance. This is to allow for imperfections in the manufactured object. It was determined through experimentation that all of the resistors that were used…

One application of magnetic fields in household appliances

One thing that uses magnetic fields is the electric motor, which is used in many household appliances, such as electric fans, microwave ovens, and other small appliances. In this instance the electric motor has an electric current, giving it also this magnetic field. An electric motor converts electricity into mechanical motion. Most electric motors work by electromagnetism, but motors based on electrostatic forces also exist. The overarching concept is that a force is generated when a current-carrying element is subjected to a magnetic field. In a cylindrical motor, the rotor rotates because a torque is developed when this force is applied at a given distance from the axis of the rotor. Most electromagnetic motors are rotary, but linear types also…

How the Length of a Wire Affects its Resistance

In my physics coursework I am going to investigate the effect of the length of a wire on its resistance. Resistance is the measure of how easy it is for current to flow through a wire. Current is the rate of flow of charge through a conductor, and it is measured in amps using an ammeter. To help me plan my investigation I have completed a preliminary experiment in which I investigated the effect of the thickness of a wire on its resistance, using three constantan wires and one copper wire. I found that the resistance increased as the thickness of the wire decreased, however, when I did the test with the copper wire I found that it was so…
