Question

How can we reduce the ripple factor of a bridge recitifier from 0.48 to 0.1 approximately ?

Answer 1

U can try to use capacitor , the value of capacitor depends on circuit

ripple factors signifies the ac components, by def its ratio of rms value of ac component to value of dc component
so in order to reduce use of a capacitor which denies the sudden changes in voltage, which is the charracteristic of Ac signals

hope this helps
