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

View answer and explanation

Correct option: A

Capacitor

Option A (Capacitor) is correct because a capacitor is used in rectifier circuits to filter out the AC ripple and provide a smoother DC output.
