| 1314359717 | electric force | The attraction or repulsion between electric charges. | 1 | |
| 1314359718 | electric field | The region around a charged object where the object's electric force interacts with other charged objects. | 2 | |
| 1314359719 | static electricity | A buildup of charges on an object. | 3 | |
| 1314359720 | conservation of charge | The law that states that charges are neither created nor destroyed but only transferred from one material to another. | 4 | |
| 1314359721 | friction | A method of charging an object by rubbing it against another object; the force that one object exerts on another when the two rub against each other. | 5 | |
| 1314359722 | conduction | A method of charging an object by allowing electrons to flow by direct contact from one object to another object. | 6 | |
| 1314359723 | induction | A method of charging an object by means of the electric field of another object; the objects have no direct contact. | 7 | |
| 1314359724 | static discharge | The loss of static electricity as electric charges transfer from one object to another. | 8 | |

| 1314359744 | voltmeter | A device used to measure voltage, or electrical potential energy difference. | 28 | |
| 1314359745 | power | The rate at which one form of energy is transformed into another; the unit of power is the watt. | 29 | |
| 1314359746 | short circuit | A connection that allows current to take an unintended path. | 30 | |
| 1314359747 | grounded | Allowing charges to flow directly from the circuit into Earth in the event of a short circuit. | 31 | |
| 1314359748 | fuse | A safety device with a thin metal strip that will melt if too much current passes through a circuit. | 32 | |
| 1314359749 | circuit breaker | A reusable safety switch that breaks the circuit when the current becomes too high. | 33 |
