Short circuit A connection that allows current to take an unintended path.
Alternating current Current consisting of charges that move back and forth in a circuit
Conductor A material through which electrons move freely, forming an electric current
Direct current Current consisting of charges that flow in only one direction in a circuit
Electric circuit A complete path through which electric charges can flow
Electric current The flow of electric charges through a material
