Rectifiers & Filters
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?
Show answer and solution
Answer: (b)
- A capacitor in parallel with the load charges near the peaks and discharges slowly between them, smoothing the output.
- So the capacitor removes the a.c. ripple. Answer (b).
