| Term | Definition |
|---|---|
| static electricity | the accumulation of excess electric charge on an object. |
| law of conservation of charge | states that charge can be transferred from one object to another but cannot be created or destroyed. |
| conductor | material such as copper wire in which electrons can move easily. |
| insulator | material in which electrons are not able to move easily. |
| charging by contact | process of transferring charge between objects by touching or rubbing. |
| charging by induction | process of rearranging electrons on a neutral objects by bringing a charged object. |
| electric current | the net movement of electric charges in a single direction, measured in amperes. |
| voltage difference | related to the force that causes electric charges to flow. |
| circuit | closed conducting loop through which an electric current can flow. |
| resistance | tendency for a material to oppose electron flow and charge electrical energy into thermal energy and light. |
| Ohm's law | states that the current in a circuit equals the voltage difference divided by the resistance.; |
| energy | the ability to cause change. |
| series circuit | circuit in which electric current has only one path to follow. |
| parallel circuit | circuit in which electric current has more than one path to follow. |
| electrical power | rate at which electricity energy is converted to another form of energy |
