Question

In a shunt capacitor filter, the mechanism that helps the removal of ripples is_________

(a) The current passing through the capacitor

(b) The property of capacitor to store electrical energy

(c) The voltage variations produced by shunting the capacitor

(d) Uniform charge flow through the rectifier

The question was asked during an interview.

My doubt stems from Capacitor Filters topic in portion Application of Diodes of Electronic Devices & Circuits

Answer 1

Right option is (b) The property of capacitor to store electrical energy

Best explanation: Filtering is frequently done by shunting the load with capacitor. It depends on the fact that a capacitor stores energy when conducting and delivers energy during non conduction. Throughout this process, the ripples are eliminated.
