Question

For a full wave rectifier, if the input frequency is 50 Hz, the output frequency will be_____
Fill in the blank with the correct answer from the options given below.

• A. 50 Hz
• B. 100 Hz
• C. 25 Hz
• D. 0 Hz

Answer 1

The Correct Option is B

To determine the output frequency of a full wave rectifier, we need to understand its operation. A full wave rectifier converts both halves of an AC waveform into a pulsating DC waveform. As a result, for every input cycle, two cycles of output are produced, effectively doubling the frequency.

Given the input frequency is 50 Hz, since the rectifier processes both the positive and negative halves of the AC input, the output frequency becomes twice the input frequency.

Therefore, the output frequency \( f_{out} \) is calculated as:

\[ f_{out} = 2 \times f_{in} \]

Where \( f_{in} \) is the input frequency, which is 50 Hz. Substituting the value, we get:

\[ f_{out} = 2 \times 50 \, \text{Hz} = 100 \, \text{Hz} \]

Thus, the correct option for the output frequency of a full wave rectifier with an input frequency of 50 Hz is 100 Hz.

Answer 2

Let's analyze the output frequency of a full-wave rectifier.

1. Full-Wave Rectifier:

A full-wave rectifier converts both halves of an AC input waveform into a pulsating DC output waveform.

2. Input Frequency (f_in):

The input frequency is given as 50 Hz.

3. Output Frequency (f_out):

In a full-wave rectifier, both the positive and negative half-cycles of the input are converted to positive half-cycles in the output. This effectively doubles the frequency of the output waveform.

f_out = 2 * f_in

f_out = 2 * 50 Hz

f_out = 100 Hz

Therefore, the output frequency of a full-wave rectifier with an input frequency of 50 Hz is 100 Hz.

The correct answer is:

Option 2: 100 Hz
