NEET 2023, Physics Q25: Semiconductors, p-n Junction Diode and Applications

NEET2023Physics
Q.

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?

  1. A

    p-n junction diodes

  2. B

    Capacitor

  3. C

    Load resistance

  4. D

    A centre-tapped transformer

Solution

A filter capacitor in parallel with the load smooths the pulsating rectified output. It charges during the peak and discharges through the load between peaks, suppressing the ripple.
