What is the output frequency of the voltage ripple produced by a full-wave bridge rectifier fed by an alternating input voltage of frequency ?
Answer and explanation
Correct answer: B.
- Step 1: In a full-wave rectifier, both the positive and negative half-cycles of the AC input are rectified into positive output pulses.
- Step 2: Consequently, two output pulses appear for every single complete cycle of the AC input: .
- Step 3: For : .
Answer
.
Why not the others: is the ripple frequency of a half-wave rectifier; divides frequency by 2; quadruples frequency.
