B & W Electricity
Electricity
| Question | Answer |
|---|---|
| Force | A push or a pull exerted on an object |
| Energy | The ability to do work or cause change |
| Potential energy | Stored energy that results from the position or shape of an object. |
| Electric force | The force between charged objects. |
| Electric field | Region around a charged object where the object's electric force is exerted on other charged objects. |
| Static electricity | The buildup of charges on an object. |
| Conservation of charge | Law stating that charges are neither created nor destroyed. |
| Friction | The transfer of electrons from one object to another by rubbing the objects together. |
| Conduction | The transfer of electrons from one object to another by direct contact. |
| Induction | When the electric field of one object causes a transfer of electrons from one part to another in the second object without the two objects touching. |
| Polarization | The process through which electrons are attracted to or repelled by an external electric field, causing the electrons to move within their own atoms. |
| Static discharge | The loss of static electricity as electric charges tranfer from one object to another. |
| Electric current | The continuous flow of electric charges through a material. |
| Electric circuit | A complete, unbroken path that charges can flow through. |
| Conductor | A material through which a charge can flow easily. |
| Insulator | A material that does not allow electrons to flow. |
| Voltage | The difference in electric potential energy per charge between two points in a circuit. |
| Resistance | The measure of how difficult it is for charges to flow through an object. |
| Ohm's Law | States that the resistance in a circuit is equal to the voltage divided by the currrent. |
| Series circuit | Circuit that has only one path for the current to take. |
| Parallel circuit | Circuit in which there are several paths for the current to take. |
| Power | The rate at which energy is transformed from one form to another. |
| Short circuit | A connection that allows current to take the path of least resistance. |
| Fuses | Devices that prevent circuits from overheating; melt if they get too hot; break the circuit. |
| Circuit breakers | Switches that bend away from a circuit as they heat up; can be reset if triggered. |
