| Question | Answer |
|---|---|
| Electric Charge | An electrical property of matter that creates electric and magnetic forces and interactions |
| Conductor | A material in which charges can move freely |
| Insulator | A material in which charges cannot move freely |
| Semiconductor | An element/compound that conducts electric current better than an insulator does, but not as well as a conductor does |
| Superconductor | A material that conducts electricity with zero resistance |
| Electric Force | The force of attraction/repulsion on a charged particle that's due to an electric field |
| Electric Field | The space around a charged object in which another charged object experiences an electric force |
| Potential Difference | The voltage difference in potential between two points in a circuit |
| Electric Current | The rate at which charges pass through a given point |
| Electric Potential Energy | The ability to move an electric charge from one point to another |
| Resistance | The opposition presented to the current by a material/device |
| Electric Curcuit | A set of electrical components connected such that they provide one or more complete paths for the movement of charges |
| Series Curcuit | A circuit in which the parts are joined one after another such that the current in each part is the same |
| Parallele Curcuit | A circuit in which the parts are joined in branches such that the potential difference across each part is the same |
| Electric Power | The rate at which electrical energy is converted into other forms of energy |
| Fuse | An electrical device that contains a metal strip that melts when current in the circuit becomes too great |
| Circuit Breaker | A switch that opens a circuit automatically when the current exceeds a certain value |
