Q63 / 75 · JEE Main 2020 (07 Jan Shift 2) · Physics

In the figure, potential difference between $A$ and $B$ is:

Correct answer
A
$10 V$
B
$5 V$
C
$15 V$
D
$0 V$

Solution

Diode is in forward bias, so it will behave as simple wire so,

So, $V_{a b} = \frac{30}{5 + 10} \times 5 = 10 V$

Hence, the correct answer is option: 'A'.
