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 ?
A centre-tapped transformer
p-n junction diodes
Capacitor
Load resistance
Capacitor works here as a filter means remove ripples from rectified DC wave .
The role of the capacitor is to filters out the AC ripple and provides pure DC output.
