What is the measurement unit for duty cycle?

The measurement unit for duty cycle is expressed as a percentage (%). The duty cycle indicates the proportion of time that a system is active compared to the total time of one cycle. For instance, a duty cycle of 50% means the system is on for half the time and off for the other half during each cycle. This metric is crucial in applications like electrofishing, where the timing of electric pulses can significantly affect the efficacy and safety of the operation.

In contrast, Hertz (Hz) measures frequency, specifically how many cycles occur per second, which does not relate directly to how long a device is on versus off. Volts (V) measures electrical potential and amperes (A) measure current, neither of which provide information about the operational timing of electrical systems. Thus, while other units quantify different electrical parameters, percentage is the appropriate way to represent the duty cycle.
