Ripple factor of half-wave rectifier is:
Correct answer: D. 1.21
- A. None of these
- B. 1.3
- C. 0.48
- D. 1.21
Explanation
Ripple factor is the ratio of the RMS value of an alternating current component in the rectified output to the average value of rectified output.Ripple factor = I'rms/IDC = V'rms/VDCFor half-wave rectifiers, ripple factor = 1.21For full-wave and bridge rectifiers, ripple factor = 0.48

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.
