If the input frequency of a full wave rectifier is \( 50 H z \) ac. Its output frequency is

1. \( 50 H z \) pulsating dc
2. \( 100 H z \) pulsating do
3. \( 200 H z \) pulsating dc
4. \( 500 H z \) pulsating dc

Correct answer: \( 100 H z \) pulsating do

Solution

In a full-wave rectifier, both the positive and negative half-cycles are converted into positive output pulses. That doubles the ripple frequency, so a 50 Hz input becomes 100 Hz at the output.
