A 100µF capacitor when used as a filter has 15V ac across it with a load resistor of 2.5KΩ. If the filter is the full wave and supply frequency is 50Hz, what is the percentage of ripple frequency in the output?
(a) 2.456%
(b) 1.154%
(c) 3.785%
(d) 3.675%
I have been asked this question in an online interview.
This interesting question is from Capacitor Filters in chapter Application of Diodes of Electronic Devices & Circuits
