Question:

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

Options:

1.3 V

2.3 V

0

0.7 V

Correct Answer:

2.3 V

Explanation:

The correct answer is Option (2) → 2.3 V

From Kirchhoff’s voltage law

$V_A-0.2 \times 10^{-3} \times 5 \times 10^3-0.3$

$-0.2 \times 10^{-3} \times 5 \times 10^3=V_B$

$V_A-V_B=1+0.3+1=2.3 ~V$
