What is the general measure of frequency in electrical terms?

The correct answer is measured in hertz. Frequency refers to the number of cycles or occurrences of a periodic event per unit of time. In electrical terms, frequency is specifically used to describe the number of wave cycles of alternating current (AC) that occur in one second. This measurement is fundamental to understanding how electrical systems operate, particularly in the context of AC power, where the frequency affects the performance of electrical devices and systems.

For example, in many parts of the world, the standard frequency for AC power is either 50 or 60 hertz, meaning that the current alternates direction 50 or 60 times per second. This measurement has significant implications for the design and functioning of electrical appliances, motors, and communication equipment.

The other options represent different electrical properties: volts measure electric potential, amps measure electric current, and ohms measure resistance. Each of these is essential for understanding various aspects of electrical systems, but they do not quantify the frequency of electrical signals.
