Electrical engineering is a part of the engineering that deals with the technology of electricity, components, devices, and systems. Electrical Engineering is a broad course because all the electric components used in that field also have smaller branches that talk about them deeply. In the past, it was a hard field because there was a scarcity of resources to improve on electronics devices. Electrical Engineering today is taking the lead because the society is taking benefit from it through devices…...

  This makes practical realization of exact phase shifts difficult, requiring high precision components. Even then maintaining constant input/output from the modulators with changing temperature and voltages is difficult. However the technique does allow low power and low cost (no filters) generation of a SSBSC signal with no need to lower the signals frequency to aid filter cut-off characteristics. As well as this the system requires less time to install and switching to lower or higher sideband is simply a…...

Diagram Preliminary results. Voltage Length of wire Current Resistance? Preliminary Conclusion. From these results it is evident that two 1. 5 Volt batteries should be used because they produce the desired range of current. However, when the length of wire is 10cm the current is too high because the temperature of the wire increased instead of staying constant. Therefore the range of the lengths in the investigation is 20cm to 100cm. These results conclude that to produce the desired range…...

Investigation to see if the length of any type of wire affects its resistance
Words • 1769

Resistance is a force. It opposes the flow of an electric current around a circuit. A circuit itself can resist the flow of particles if the wires are either very thin or very long. E.g. the filament across an electric bulb is very thin, as it needs to resist the flow of particles so that the bulb can glow. Resistance is measured in ohms. This discovery was made by George Ohm. He found out that the voltage of a circuit…...

We have been asked to investigate how the length of two different pieces of wire, Nichrome and Constantin effects the resistance. These are both metal alloys and they both conduct electricity. Metals conduct electricity because the atoms in them don't hold on to their electrons very well, so allowing electrons to move carrying a negative charge along the wire. Resistance occurs when it is difficult for the electrons to be released from their nuclei to continue along the piece of…...

Semiconductors usually have four electrons in the outer electron shell. They are tetravalent. These are called valence electrons. The structure that is formed is a tetrahedral structure. This forms a crystalline structure. There are two types of semiconductors. One type is the intrinsic semiconductors and the extrinsic semiconductors. Intrinsic semiconductors are elements and compounds that are semiconductors. Examples include Silicon and Cadmium. When they are in a solid state, the silicon atoms form a covalent bond among themselves to form…...
