In a rectifier, the larger the value of the shunt capacitor filter, _.
Correct answer: C. Longer the time the current pulse flows through the diode
- A. Larger the peak-to-peak value of the ripple voltage
- B. Larger the peak current in the rectifying diode
- C. Longer the time the current pulse flows through the diode
- D. Smaller the voltage across the load
Explanation
C= ΔQ/ΔV = I x t/ΔVIf C increases, t increases for constant input power and voltage. Hence the time t for which current flows through the diode increases.

About Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
