✔✔ alternating - ✔✔____ current is current that reverses its direction of flow at regular
intervals.
✔✔voltage - ✔✔____ is the amount of electrical pressure that causes electrons to move
in a circuit.
✔✔amperes - ✔✔Current is measured in ____.
✔✔OCPD - ✔✔A(n) ____ is a device that automatically opens a circuit to prevent
damage from a high-current condition.
✔✔contact - ✔✔A(n) ____ is the conducting part of a switch that operates with another
conducting part to complete (close) or break (open) a circuit.
✔✔relay - ✔✔A(n) ____ is an electrical switch that is actuated by a separate circuit.
