In a rectifier, larger the value of hunt capacitor filter
Correct answer: C. Longer the time that current pulse flows through the diode
- A. Larger the peak-to-peak value of ripple voltage
- B. Larger the peak current in the rectifying diode
- C. Longer the time that current pulse flows through the diode
- D. Smaller the voltage across the load
Explanation
The time constant for a capacitor has the value RC, where R is the load resistance and C is the shunt capacitor's capacitance. As C increases, RC increases so, it takes a longer time for the current pulse to flow through the diode.

About Rectification
Rectification converts alternating current into unidirectional current using semiconductor diodes. The content includes half wave and full wave rectifiers, bridge circuits, output waveforms, ripple and smoothing with capacitors, with the difference between rectification and voltage regulation kept clear.
