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) |
