Parallel Circuit an electric circuit in which electricity has multiple paths to follow
Switch Turns a circuit on and off
Conductor a material that allows electricity and thermal energy to pass through easily (usually metal)
Insulator a material that does NOT allow electricity or thermal energy to pass through easily (plastic, rubber, cloth, wood, Styrofoam)
