| Questions | Answers |
|---|---|
| Electricity | The flow of electrons. |
| Potential Difference | A measure of how much potential energy an electron has in one place compared to another place. The correct name for what is often called "voltage" or "electromotive force." |
| Amps | Measurement of current flow through a conductor. |
| Conductor | A substance or material that allows electrons, or electrical current, to flow through it. |
| Circuit | The path followed by a flow of electric current. |
| Power | Energy used to do work measured in watts. |
| Ohm | A unit of electrical resistance defined as the resistance of a circuit with a voltage of one volt and a current flow of one ampere. |
| Volt | A unit of electromotive force. The electrical potential needed to produce one ampere of current with a resistance of one ohm. |
| Current | The movement of electrons in a conductor measured in Amperes. |
| Joule | 1) Work done by the force of one neutron when its point of application moves through the distance of one meter in the direction of the force. 2) One watt-second. |
| Watt | A unit for measuring electric power. |
| Charge | Electricity produced by a surplus or a shortage of electrons in an object. |
| Proton | A basic particle in an atom's nucleus that has a positive charge. |
| Electron | A negatively charged particle that orbits the nucleus of an atom. The flow of electrons produces electricity. |
| Neutron | A basic particle in an atom's nucleus that has a neutral electrical charge. |
| Resistance | The opposition to current flow, expressed in ohms. |
| Direct Current | Electric current in which electrons flow in one direction only. Opposite of alternating current. |
| Alternating Current (AC) | Electric current that reverses directions at regular intervals. |
| Insulator | Any material that will not allow electricity to easily flow through. |
