| A | B |
| circuit | is a path containing easily moveable charges |
| current | the flow of electrical charge |
| open circuit | a circuit that has a break that prevents the flow of current |
| closed circuit | a circuit that has a complete path for charge to flow. |
| metal wire current | current is the flow of negatively charged particles (electrons). |
| battery, your body, or other wet places | current is the flow of both positive and negative charges. |
| fuse | a safety device that melts when current is too high, breaking a circuit |
| insulator | a material that does not contain easily moveable charges |
| short circuit | an unwanted electrical connection with very low resistance to current |
| parallel circuit | a circuit that contains two or more branches |
| series circuit | a circuit where moving charges can only follow a single path |
