| circuit | a complete path through which an electric current can flow |
| current | the flow of electricity; a measure of the flow of electrons around a circuit |
| series circuit | a circuit in which there is only 1 pathway along which the current can travel |
| parallel circuit | circuit in which there is more than 1 pathway along which the current can travel |
| component | a part in an electrical circuit, e.g. bulb, wire, switch |
| switch | a device used to open a circuit or to divert current from 1 conductor to another |
| ammeter | a device that detects and measures electrical current |
| ampere / amp (A) | the unit used to measure the amount of electric current |
| variable resistor | an electronic component that can be adjusted to give different to give different amounts of electrical resistance |
| fuse | a safety device placed in a circuit that melts and breaks if too much current flows |
| *terminal | one of the points at which you can connect wires in an electrical circuit |
| *ohm | a measurement of resistance in an electrical circuit |
| *junction | a place where two or more cables, etc. meet or are joined |
