Question

In the circuit shown in figure, if the diode forward voltage is 0.3 V, the voltage difference between A and B

(a) 1.3 V

(b) 2.3 V

(c) 0

(d) 0.5 V

Answer 1

The correct option is (b) 2.3 V.

Explanation:

Let V be the potential difference between A and B, then

 V - 0.3 = (5 +5) x 10³ x (0.2 x 10^-3) =2 

or V = 2 + 0.3 = 2.3 V
