a safety device consisting of a strip of wire that melts and breaks an electric circuit if the current exceeds a safe travel | Fuse |
a circuit where the electrons have many paths to take. | Parallel Circuit |
an electric current in which electrons have only one path to take. | Series Circuit |
source or cell | Battery |
a path along which electric charges can flow | Circuit |
the path must go from the energy source to the device and back again to keep the charges moving | Complete circuit |
closing or turning the switch "on," closes the gap | Closed circuit/switch |
opening a switch in a circuit causes a gap, so charges can't flow | Open circuit/switch |
a material that allows electricity or heat to pass through it easily | Conductor |
a material that does NOT allow electricity or heat to pass through it easily | Insulator |
turns a circuit on and off | Switch |
