Question

In a full wave rectifier, if input frequency is 50 Hz, then output frequency will be:

• A. 25 Hz
• B. 50 Hz
• C. 100 Hz
• D. 200 Hz

Hint:

Full-wave rectifiers double the input AC frequency in their output.

Answer 1

The Correct Option is C

A full-wave rectifier converts both the positive and negative half cycles of an alternating current (AC) input into positive half cycles at the output. This process effectively inverts every negative half cycle, resulting in an output signal whose frequency is twice that of the input AC signal. Given the input frequency is 50 Hz, the output frequency after full-wave rectification is: \[ \text{Output frequency} = 2 \times 50 = 100 \text{ Hz}. \]
