| circuit | continuous unbroken path |
| conductor | allows electricity to flow through easily |
| electric cell | produces an electric current using 2 metals and a solution |
| electrical signal | electric current that carries information |
| electrolyte | liquid that conducts electricity |
| electromagnet | coil of wire with a core attached to electrical source |
| insulator | does not allow electricity to flow through |
