Ncert Exercises & Solutions

To reduce the ripples in rectifier circuit with capacitor filter:

(a)	\(R_L\) should be increased
(b)	input frequency should be decreased
(c)	input frequency should be increased
(d)	capacitors with high capacitance should be used

Choose the correct option:

1.	(a), (c)	2.	(b), (d)
3.	(a), (c), (d)	4.	(b), (c), (d)

(3) Hint: Ripple factor is inversely proportional to R_L, C and v.

To reduce r, R_L should be increased, input frequency should be increased and capacitance C should be increased.
