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

Options

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

Answer

To solve the problem of determining the output frequency of a full wave rectifier when the input frequency is given, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Full Wave Rectification**:
- A full wave rectifier converts both halves of the AC input signal into DC output. This means that for every cycle of the input signal, there are two cycles of the output signal.

2. **Identify the Input Frequency**:
- The problem states that the input frequency (f_in) is 50 Hz.

3. **Determine the Relationship Between Input and Output Frequency**:
- For a full wave rectifier, the output frequency (f_out) is twice the input frequency. This is because each half of the AC waveform contributes to the output.

4. **Calculate the Output Frequency**:
- Using the relationship:
\[ f_{out} = 2 \times f_{in} \]
- Substitute the given input frequency:
\[ f_{out} = 2 \times 50 \text{ Hz} = 100 \text{ Hz} \]

5. **Conclusion**:
- Therefore, the output frequency of the full wave rectifier is 100 Hz.

### Final Answer:
The output frequency of the full wave rectifier is **100 Hz**.
