To reduce the ripples in a rectifier circuit with capacitor filter (a) RL should be increased (b) input frequency should be decreased (c) input frequency should be increased (d) capacitors with high capacitance should be used
Ripple factor ( r ) of a full wave rectifier using capacitor filter is given by : r=43RLCv1 Thus to reduce r,RL should be increased, input frequency v should be increased and capacitance C should be increased
