What measurement unit is commonly used for the frequency of an electrical signal?

The measurement unit commonly used for the frequency of an electrical signal is Hertz. Frequency refers to the number of cycles of an electric signal that occur in one second. Hertz (Hz) quantifies this frequency measurement, where one hertz is equivalent to one cycle per second. This unit is pivotal in various fields of electronics and signal processing because it helps in understanding how often a signal oscillates, which is crucial for audio signals, radio frequencies, and various types of communication technologies.

In contrast, Ohms is the unit of measurement for electrical resistance, Volts measure electrical potential or voltage, and Watts quantify electrical power. Each of these units serves a distinct purpose within the realm of electrical engineering and electronics, but Hertz specifically addresses the frequency aspect, making it the appropriate choice in this context. Understanding frequency is essential for a Biomedical Equipment Technician, as it relates to many medical devices and their performance.
