Q. A silicon diode has a threshold voltage of 7 V. If an input voltage given by 2 sin ($\pi\ t$) is supplied to a half-wave rectifier circuit using this diode, the rectified output has a peak value of
A) 2 V
B) 1.4 V
C) 1.3 V
D) 0.7 V
Explanation
(c) Peak value of rectified output voltage
= peak value of input voltage $–$ barrier voltage
= 2 $–$ 0.7 = 1.3 V
