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?
load resistance
a centre-tapped transformer
p-n junction diodes
capacitor
In a rectifier circuit, the pulsating DC output contains AC ripples. A capacitor is connected in parallel with the load resistance to act as a filter. It charges during the peak of the voltage and discharges through the load when the voltage falls, thereby smoothing out the fluctuations and removing the AC ripple from the rectified output.
