Electrostatics Paper

Electrostatics is a part of physics is that the study and analysis of electricity, its properties and its applications. Electrostatics was discovered when an ancient Greek philosopher named Thales. In 600 B.C., Thales learned that when he rubbed amber with fur, it would start to attract other lightweight objects such as feathers and dust which is now known as a process called triboelectrification. This is also how we got the word electricity, which comes from the Greek word, elektron, which means amber. Thales, who is now known as one of the Seven Wise Men, is believed to be the first person to ever experiment with electrostatics. After the death of Thales, no further experiments were conducted dealing with electrostatics until…

What’s the Buzz on Smart Grids?

1.How do smart grids differ from the current electricity infrastructure in the United States? Smart Grids Advantages: A smart grid delivers electricity from suppliers to consumers using digital technology to save energy, reduce costs, and increase reliability and transparency. The smart grid enables information to flow back and forth between electric power providers and individual households to allow both consumers and energy companies to make more intelligent decisions regarding energy consumption and production. Information from smart grids would show utilities when to raise prices when demand is high and lower then when demand lessens. Smart grids would also help consumers program high-use electrical appliances like heating and air conditioning systems to reduce consumption during times of peak usage. If implemented…

Load Sheeding

Power generators have limited capacities. When demand of electricity in a certain area exceeds its generation, the supply is to be cut temporarily as a method of reducing the demand on the generators. This temporary reduction in electricity supply is known as load shedding and less formally power cut. Peak load shedding hours are early evenings and mornings when most bulbs are lit and most home appliances are in use. Power is a very important daily need of modern life. Without it, life cannot run normally. Radios, TVs, computers, rice cookers and other home appliances don’t operate. With power cut, supply of drinking water, etc. is halted. Rooms cannot be heated or cooled. Records are lost and valuable machines break…

AC Circuits

Discussion In the experiment AC circuits, the purpose was to see the effect that a capacitor, resistor, and inductor have on the voltage, and current of a circuit. We created circuits with 2 resistors, a capacitor and a resistor, and then a capacitor, resistor, and an inductor. The circuits were then hooked up to a function generator, and oscilloscope to find the voltage across certain frequencies and then calculate the peak current, capacitive reactance or the inductive reactance, and phase difference. When beginning the experiment, we measured the resistance of both resistors with a digital multi-meter and received values for R1 as 559 Ω +or- 10 Ω and for R2 as 108 Ω +or- 10 Ω. After measuring the resistance,…

How to Find an Earth Fault on Board Ships?

Earth fault is considered very critical on board a ship. Some ships which operate at 440 V do not have any trip devices attached for a single earth fault. However when the operating voltage exceeds 3000V, it is mandatory to have a protection system which isolates when a machinery suffers an earth fault. How to find out an Earth Fault? The seriousness of the action to be taken on an Earth Fault depends on the part of the electrical system it affects. Conventional ships which operate on 3 Phase, 440V, have earth fault indicators installed on all three phases. Any earth fault on a 440V system is considered to be a serious trouble and immediate action is required to identify…

Power Reforms

Electricity is central to achieving economic, social and environmental objectives of sustainable human development. In fact it has become essential ingredient for improving the quality of life and its absence is usually associated with poverty and poor quality of life. India has the fifth largest generation capacity in the world with an installed capacity of 173,626 MW as in March 2011. The power sector added record conventional capacities of 12,160 MW during 2010-11. However, despite the Indian power sector having shown substantial growth during the post-independence era, the sector has been ailing from serious functional problems during the past few decades. In 2010-11, India faced power deficit of 10 per cent and peak demand shortage of 13.3 per cent. In…

Cells: The Building Blocks of Life

Cells are the basic building blocks of life. For cells to survive and function normally, fluids and electrolytes must keep a harmonious balance. The human body is composed of approximately 60% electrolyte-containing water, in which it is the kidneys’ job to regulate. Any loss of water should be matched with a consumption of water on a daily basis to ensure cells receive a constant balance of fluids. Water from our bodies comes from foods and liquids. Water loss is mostly through urine and is also lost in sweat, respiratory tract and feces. The kidneys produce large amounts of urine when water intake is high to maintain a balance. When our bodies lose water the kidneys will retain water which produce…

Importance of electrical services in buildings

Electricity has been part of our lives. It has brought many things that surely have made many wonders and life would seem so hard without it. Electricity powers our light, heating, electronic appliances such as computers and television, and a host of essential services that we take for granted. However, electricity has much more important aspects because it is a fundamental feature of all matter. Electricity is the force that holds together the molecules and atoms of all substances. The type of electricity that is most familiar to us is electrical current. This is the flow of electrical charges through a substance called a conductor such as a metal wire. This flow happens beacuse some of the negatively charge electrons…

Electrical Circuit

1. Conductor – is a material which contains movable electric charges. In metallic conductors such as copper or aluminum, the movable charged particles are electrons (see electrical conduction). Positive charges may also be mobile, such as the cationic electrolyte(s) of a battery, or the mobile protons of the proton conductor of a fuel cell. In general use, the term “conductor” is interchangeable with “wire. 2. Insulators – are non-conducting materials with few mobile charges and which support only insignificant electric currents. 3. Atom – is a basic unit of matter that consists of a dense central nucleus surrounded by a cloud of negatively charged electrons. The atomic nucleus contains a mix of positively charged protons and electrically neutral neutrons (except…

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…

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…
