Question:
If the output frequency of a full-wave rectifier is 100 Hz, then input frequency will be ______.
If the output frequency of a full-wave rectifier is 100 Hz, then input frequency will be ______.
Show Hint
In a \textbf{Half-Wave} Rectifier, $f_{out} = f_{in}$. In a \textbf{Full-Wave} Rectifier, $f_{out} = 2f_{in}$.

The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
A full-wave rectifier converts both halves of the AC cycle into pulsating DC. This effectively doubles the frequency of the "pulses" compared to the original wave.
Step 2: Detailed Explanation:
For a Full-Wave Rectifier: $f_{out} = 2 \times f_{in}$.
Given $f_{out} = 100\text{ Hz}$.
$$100 = 2 \times f_{in} \implies f_{in} = 50\text{ Hz}$$
Step 3: Final Answer:
The correct option is (a).
