Science Electricity and Magnetism test
| Question | Answer |
|---|---|
| Static Electicity | The accumulation of electric discharge that occurs when two non-metallic objects rub against each other. |
| Example of Static Electricity | Rubbing a balloon and then sticking it to a wall |
| Dynamic Electricity | The flow of electric charges through a conductor |
| Electric Potential | The amount of work that could be done |
| Current | The flow of electric charge |
| Voltage | The amount of potential difference |
| Resistance | The amount of difficulty encountered by a power source in forcing electric current through an electric circuit |
| Electric Charge | The physical property of matter that causes it to experience a force when placed in an electromagnetic field |
| Conductor | Allows electric current to flow freely |
| Insulator | Material that does not allow electric charges to flow freely |
| Voltage | Measured in volts (V) |
| Resistance | measured in ohms (R) |
| Current | measured in amps (I) |
