Consider a peak rectifier fed by a 60-Hz sinusoid having a peak value Vp = 100V. Let the load resistance R = 10kΩ. Calculate the fraction of the cycle during which the diode is conducting:
Correct answer: C. 3.18 %
- A. 1.06 %
- B. 2.06 %
- C. 3.18 %
- D. 4.82 %
Explanation
The correct answer is Option C: 3.18 %The best I can explain: w Δt ~ √(2Vr/Vp)Θ = √(2 X 2/100)Θ = 0.2 rad or 3.18 % of the cycle.

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.
