Definitions:

Clamp-On Ammeter

A type of ammeter that can measure a wire's current without the need to disconnect it from the circuit, by clamping around the wire.

True Power

The actual power consumed by a circuit, measured in watts, as opposed to apparent power, which includes reactive power.

Series RC

A circuit configuration consisting of a resistor (R) and a capacitor (C) connected in a series arrangement.

Apparent Power

The total power in an AC circuit, equal to the product of the voltage and current, measured in volt-amperes (VA).
