If the input frequency of a full-wave rectifier is 50 Hz, its ripple frequency is:
Correct answer: D. 100 Hz
- A. 25 Hz
- B. None of these
- C. 50 Hz
- D. 100 Hz
Explanation
The ripple frequency of a full-wave rectifier is twice its input frequency. Since the input frequency is 50 Hz, the ripple frequency would be 50x2=100 Hz.The diagram shows how the wave is, first, rectified, to give all wave crests, doubling the frequency. Ripples are formed due to the action of capacitors to smooth the circuit.

About Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
