| electric circuit | path that an electric current follows |
| series circuit | circuit in which electric current follows only one path |
| parallel circuit | circuit in which an electric current can follow more than one path |
| voltage | energy available to move charges through a circuit |
| volt | unit used to measure voltage |
| ampere | unit used to measure electric current |
| resistance | opposition to the flow of electric current |
| ohm | unit used to measure resistance |
| Ohm's law | current in a wire is equal to the voltage divided by the resistance |
| fuse | thin piece of metal that melts and breaks a circuit if too much current is flowing |
| circuit breaker | switch that opens a circuit if too much current is flowing |
