Question

Ripple factor of a half wave rectifier is_________(Im is the peak current and RL is load resistance)

(a) 1.414

(b) 1.21

(c) 1.4

(d) 0.48

The question was posed to me by my college director while I was bunking the class.

I'm obligated to ask this question of Half-Wave Rectifier in section Application of Diodes of Electronic Devices & Circuits

Answer 1

The correct choice is (b) 1.21

To explain I would say: The ripple factor of a rectifier is the measure of disturbances produced in the output. It’s the effectiveness of a power supply filter to reduce the ripple voltage. The ratio of ripple voltage to DC output voltage is ripple factor which is 1.21.
