Vedclass · Answer

(B) filter circuit is an electronic circuit designed to remove the unwanted $AC$ components (ripples) from the pulsating $DC$ output obtained from a rectifier. It typically consists of passive components like capacitors $(C)$,inductors $(L)$,or a combination of both ($LC$ or $\pi$-filters). The capacitor acts as a low-impedance path for $AC$ ripples to ground,while the inductor blocks $AC$ ripples due to its high inductive reactance $(X_L = 2\pi fL)$. Thus,the filter circuit helps in obtaining a smooth,steady $DC$ voltage across the load.
