Electrical terms

3. The rate at which electric charge flows through a conductor.
4. an electric current flowing in one direction only.
7. The measure of opposition to the flow of current within a material or component.
8. an automatic safety switch designed to protect electrical circuits from damage caused by overload or short circuits.
10. low-resistance connection between a live electrical conductor and the ground.
12. The electrical pressure or potential energy difference between two points in a circuit that forces charge to move.
13. an electric current that periodically reverses direction and changes magnitude over time.
14. a brand name for non-metallic sheathed electrical cable

1. A material that allows electricity to flow through it easily because it has many free, unbound electrons.
2. the intentional connection of an electrical circuit to the earth, creating a low-resistance path for excess electricity to follow.
5. A closed, continuous path or loop through which electric current.
6. a passive electrical device that transfers energy between circuits by increasing or decreasing.
9. A material that resists the flow of electricity and acts as a barrier.
11. electrical circuit of lower resistance than that of a normal circuit.
