VAC - Volts of alternating current
Varistor - A semiconductor device whose resistance varies with the applied voltage
Volt (V) - The unit of voltage or potential difference
Voltage - Electrical pressure, or electromotive force (EMF). The force that causes current to flow through a conductor, expressed as a difference of potential between two points, since it is a relational term. Connecting both voltmeter leads to the same point will show no voltage present, although the voltage between that point and ground may equal hundreds or thousands of volts. Thus, most nominal voltage are expressed as phase to phase or phase to neutral. The unit of measurement is volts and the electrical symbol is V. |
