The frequency of an alternated circuit is measured by the number of times the currents and/or voltages change direction (polarity) in a unit of time. The Hertz is the universally accepted unit of frequency, and measures cycles per second. One ALTERNATED CIRCUITS (AC)7 Fig. 1.6Electrical-mechanical equivalence. Hz equals one cycle per second.
