| Question |
Answer |
| amperes (A) |
The unit used to measure the amount of current that flows past a point in one second. |
| capacitors |
Objects or devices that store an electric charge. |
| circuit |
A circular conducting path. |
| circuit breaker |
A safety device that switches to break a circuit if current becomes too high. |
| coulomb (C) |
The unit of electrical charge. |
| electric current |
Electricity that involves continuously moving charges. |
| electroscope |
A device that detects charges. |
| fuses |
Safety devices that melts to break a circuit if current becomes too high. |
| induction |
Charging an object by shifting the paths of its electrons. |
| kilowatts (kW) |
1000 watts. |
| law of charges |
Like charges repel; unlike charges attract. |
| loads |
The resistive devices in an electrical circuit. |
| ohms |
The unit used to measure resistance. |
| parallel circuit |
A circuit with two or more paths for the electrons in it to follow. |
| resistor |
Any object that resists the flow of electricity. |
| Semiconductors |
A substance that holds its electrons in a way that allows a partial flow of electricity. |
| series circuit |
A circuit with a single path for all the electrons in it to follow. |
| short circuit |
A situation in which an electrical current passes through a path shorter than the entire circuit. |
| static electricity |
The effects produced by stationary charges. |
| switch |
A device that can be used to break (open or close) a circuit. |
| volts (V) |
The difference between electrical potentials. |
| watt (W) |
The Sl units of power; 1 joule of energy per second. |
