| Law of electric charges | The law that states that like charges repel and opposite charges attract |
| Electric Force | The force between charged objects |
| Conduction | A method of charging an object that occurs when electrons are transferred from on object to another by direct contact |
| Induction | A method of charging an object that occus when charges in an uncharged object are rearranged without direct contact with a charged object |
| Conductor | A material in which charges can move easily |
| Insulator | A material in which charges cannot easily move |
| Static electricity | The buildup of electric charges on an object |
| Electric Disccharge | The loss of static electricity as charges move off an object |
| Cell | A device that produces an electric current by converting chemical energy into electrical energy |
| Battery | A device that is made of serval cells and that produces an electric current by converting chemical energy into electrical energy |
| Potential Difference | Energy per unit charge; specially, the difference in energy per unit charge as a charge moves between two points in an electric circuit (same as voltage); expresses in volts (V) |
| Photocell | The part of a solaar panel that converts light into electrical energy |
| Thermocouple | A device that converts thermal energy into electrical energy |
| Current | The rate at which charge passes a given point; expressed in amperes (A) |
| Voltage | The difference in energy per unit charge as a charge moves between two points in an electric circuit (same as potential difference); expresses in volts (V) |
| Resistance | The opposition to the flow of electric charge; expresses in ohms |
| Electric power | The rate at which electrical energy is used to do work; expressed in watts (W) |
| Circuit | A complete, closed path through which electric charges flow |
| Load | A device that uses electrical energy to do work |
| Series circuit | A circuit in which all parts are connected in a single loop |
| Parallel Circuit | A circuit in which different loads are located on separate branches |
