The measure of the number of cycles per second of the voltage produced by an AC generator is called the frequency of that voltage and is measured in what unit?

The correct response is that the frequency of the voltage produced by an AC generator is measured in Hertz. Hertz is the unit that quantifies cycles per second and is fundamental in AC electricity, as it defines how many times the current alternates direction in one second. In the context of electrical systems, the frequency is crucial because it affects how electrical devices operate, including how they interact with the power supply.

For example, in North America, electrical systems typically operate at a frequency of 60 Hertz, meaning the current alternates 60 times per second. This parameter is essential for ensuring that electrical devices function correctly and safely within their designed operational parameters.

The other units listed do not measure frequency: Watts quantify power, Amperes measure current, and Ohms denote resistance. Each of these plays a vital role in electrical systems, but Hertz specifically pertains to the measurement of cycles per second of AC voltage.
