| an electrical property of matter that creates a force between objects | electric charge |
| material that transfers charge easily | conductor |
| material that does not transfer charge easily | insulator |
| force of attraction or repulsion between objects due to charge | electric force |
| region around a charged object in which other charged objects experience an electric force | electric field |
| potential energy of a charged object to its position in an electric field | electrical potential energy |
| CHANGE in the electrical potential energy per unit charge | potential difference |
| device that is a source of electric current because of a potential difference, or voltage, between the terminals | cell |
| rate that electric charges move through a conductor | current |
| ratio of the voltage across a conductor to the current it carries | resistance |
| electrical device connected so that it provides one or more complete paths for the movement of charges | electric circuit |
| graphic representation of an electric circuit or apparatus, with standard symbols for the electrical devices | schematic diagram |
| circuit or protion of a circuit that provides a single conducting path | series |
| components in a circuit that are connected across common points, providing two or more separate conducting paths | parallel |
