In half - wave rectification, what is the output frequency, if the
input frequency is 50 Hz ? What is the output frequency of a full - wave rectifier
for the same input frequency ?

Explanation

To solve the question about the output frequency of half-wave and full-wave rectifiers given an input frequency of 50 Hz, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Half-Wave Rectification**:
- A half-wave rectifier allows only one half (positive or negative) of the AC waveform to pass through, effectively blocking the other half.
- Therefore, the output frequency of a half-wave rectifier is the same as the input frequency.

**Calculation**:
- Input frequency = 50 Hz
- Output frequency (half-wave) = Input frequency = 50 Hz

2. **Understanding Full-Wave Rectification**:
- A full-wave rectifier allows both halves of the AC waveform to pass through, but it inverts the negative half to make it positive.
- This means that for every complete cycle of the AC input, there are two cycles of output in a full-wave rectifier.

**Calculation**:
- Input frequency = 50 Hz
- Output frequency (full-wave) = 2 × Input frequency = 2 × 50 Hz = 100 Hz

### Final Answers:
- The output frequency of the half-wave rectifier is **50 Hz**.
- The output frequency of the full-wave rectifier is **100 Hz**.
