What is the ripple frequency of a full-wave single-phase bridge rectifier operating at 60Hz?

In a full-wave single-phase bridge rectifier, the output frequency of the ripple voltage is influenced by the input frequency of the AC supply. For a full-wave rectifier, the output frequency is twice the input frequency. Since the question specifies an input frequency of 60Hz, the ripple frequency can be calculated as follows:

Ripple frequency = 2 × Input frequency

Ripple frequency = 2 × 60Hz = 120Hz

This means that for every cycle of AC input, the rectifier produces two pulses of DC output, effectively doubling the frequency at which the ripple occurs. Therefore, the correct answer is 120Hz, as indicated. The ripple frequency plays a critical role in determining the performance of the rectifier circuit and influences the choice of filtering components in subsequent stages.
