| 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. |
