| electric current | the flow of negative charges through a material |
| insulators | prevents the flow of electricity |
| conductors | allows the flow of elctricity |
| current electricity | carried by wires |
| copper | most common metal used as a conductor |
| good insulators | rubber, wood, glass, and certain plastics |
| good conductors | materials containing metal |
| series circuit | removing anything in this path will interrupt the flow of electricity |
| parallel circuit | most homes are wired this way |
| switches | allows you to open and close a circuit |
