Question

Consider a peak rectifier fed by a 60-Hz sinusoid having a peak value Vp = 100 V. Let the load resistance R = 10 kΩ. Calculate the fraction of the cycle during which the diode is conducting

(a) 1.06 %

(b) 2.12 %

(c) 3.18%

(d) 4.24%

This question was addressed to me by my school principal while I was bunking the class.

This intriguing question comes from Rectifiers topic in chapter Diodes of Electronic Devices & Circuits

Answer 1

The correct option is (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
