  • 50 Hz
  • 100 Hz
  • 25 Hz
  • 0 Hz
Show Solution

The Correct Option is B

Solution and Explanation

A full wave rectifier processes both halves of an AC waveform, converting them into a pulsating DC waveform. This operation results in two output cycles for every input cycle, effectively doubling the frequency.
For an input frequency of 50 Hz, the full wave rectifier doubles this value.
The output frequency \( f_{out} \) is determined by the formula:
\[ f_{out} = 2 \times f_{in} \]
Given \( f_{in} = 50 \, \text{Hz} \), the calculation is:
\[ f_{out} = 2 \times 50 \, \text{Hz} = 100 \, \text{Hz} \]
Consequently, the output frequency of a full wave rectifier with an input of 50 Hz is 100 Hz.
