Conductor – Materials that allow the flow of electrons easily, including silver, copper, gold, and aluminum. Electrical wires are mostly made of copper, some are made of aluminum.

A device designed to open and close a circuit by nonautomatic means and to open the circuit automatically on a predetermined overcurrent without damage to itself when properly applied within its rating. (Example: The circuit breaker will trip during a short circuit, ground fault, and overload condition.)

Circuit – Circuit breaker(s), conductors (wires), and electrical outlets. Conductors in a circuit contain line, neutral, and ground conductor(s). Older systems may not contain ground conductors.

Arc Fault – An abnormal condition where an arc occurs (corroded or loose connection).

Atom The smallest unit of matter.  Everything in the world is made of different combinations of atoms.

Ampacity: There is a maximum amount of electric current that a device can carry.

Ammeter: It is possible to measure the flow of electrical current. When a circuit gets tested, connect an ammeter in series.

Appliance: an item of electrical current-using equipment.

AC Current: AC stands for alternating current. At regular intervals, this is an electric current that changes direction many times a second.
