Vedclass · Answer

(D) In a rectifier circuit,the output contains $AC$ ripples (fluctuations). To obtain a smooth $DC$ output,a filter circuit is used. $A$ capacitor is connected in parallel with the load resistance to act as a filter. The capacitor charges when the output voltage increases and discharges through the load when the output voltage decreases,thereby smoothing out the ripples. Therefore,the capacitor is the component that removes $AC$ ripples from the rectified output.

$A$ full wave rectifier circuit consists of two $p-n$ junction diodes,a centre-tapped transformer,a capacitor,and a load resistance. Which of these components removes the $AC$ ripple from the rectified output?
