Question

If the input frequency is 50 Hz, the output frequency of a full wave rectifier is: 
 

• A. 75 Hz
• B. 25 Hz
• C. 50 Hz
• D. 100 Hz

Hint:

A full-wave rectifier doubles the frequency of the AC input because it allows current to flow through the load during both halves of the cycle, essentially converting negative cycles to positive.

Answer 1

The Correct Option is D

A full-wave rectifier inverts every half-cycle of the AC input signal, effectively doubling the frequency of the input AC signal. 
Therefore, if the input frequency is 50 Hz, the output frequency of a full-wave rectifier will be: \[ 2 \times 50 \, {Hz} = 100 \, {Hz} \]
