NEET (UG) 2023 — Question 176
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?
- Option A:
p-n junction diodes
- Option B:Correct
Capacitor
- Option C:
Load resistance
- Option D:
A centre-tapped transformer
Answer: B
Step-by-step solution
The capacitor acts as a filter. During charging, it stores charge when the rectified voltage rises and discharges through the load when the voltage falls, thereby smoothing out the AC ripple. This is why a capacitor is used in a full-wave rectifier to remove ripple.
