Electrical Engineering Subtopics
Electric Wire Materials
- Copper electrical wire - Copper (Cu) is considered the standard in wiring. Most homes and appliances use copper for two reasons. It is easy to mold or bend and it is a good conductor. Copper is rather easy to come by but not as easy as other conductor metals.
- Aluminum electrical wire - Aluminum (Al) is also easy to mold and bend but less of a conductor than copper. If you decide to use aluminum wire that will carry the same amount of electricity as a copper wire, the wire needs to have a larger diameter. Since aluminum is more abundant than copper, it makes it the cheaper of the two.
- Silver electrical wire - Silver (Ag) is the best conductor of electricity for high temperatures. However, it is hard to bend and expensive.
- Alloys in electrical wire - In manufacturing, an alloy may sometimes be used. Aluminum and copper can be used for cost and conductibility.

- Frequency - The number of cycles per sec, measured in Hertz.
- Fuse - An safety device that removes electrical current from a circuit when the current is two high.
- Generator - A mechanical device that produces electrical energy from mechanical energy.
- Hertz - A measure of frequency or cps (cycles per second).
- Horsepower - A measure of power or the rate of doing work.
- Magnetic field - Magnetic fields never cross, never start or stop, where the field is strongest lines bunch togeather and can be seen clearly seen in the real world.
- Magnetic flux (\(\phi\) or \(\phi_B\)) - The number of magnetic field lines passing through a given closed surface.
- Magnetic switch - Depending on the switch configuration for on and off, the switch is activated when the magnetic field is detected.
- Normally closed (NC) - The circuit is closed when the switch is not open.
- Normally open (NO) - The circuit is open when the switch is not operated.
- Ohm - A unit of resistance.
- Ohm's law - The relationships between power, voltage, current, and resistance.
