The ripple factor of half-wave rectifier is?
Correct answer: A. 1.21
- A. 1.21
- B. 0.8
- C. 0.6
- D. 0.4
Explanation
Ripple factor determines how well a half-wave rectifier can convert AC voltage to DC voltage. The ripple factor is a measure of the effectiveness of a power supply filter, in this case, a half-wave rectifier. It's a measure of the amount of AC component (ripple) in the output DC signal. The ripple factor is defined as the ratio of the root mean square (rms) value of the ripple voltage to the absolute value of the DC component of the output voltage. For a half-wave rectifier, the ripple factor is theoretically calculated as 1.21 (or 121% if expressed as a percentage). This is because a half-wave rectifier only allows one half of the AC signal to pass through, leading to a significant ripple in the output. Without additional information about the specific rectifier or any filtering applied, the correct answer to this question would be A) 1.21, as this is the theoretical ripple factor for a half-wave rectifier.

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.
