Question

A full-wave rectifier with two p–n diodes is connected to a centre-tapped transformer, capacitor and load resistance. Which component should be used to remove ripples?

G1 Physics · Accepted Answer

Rectification converts AC to pulsating DC. A smoothing capacitor charges near output peaks and discharges through the load between peaks. This reduces ripple and creates a steadier DC voltage. Final answer: Option A.
