Question:
In the figure, potential difference between $A$ and $B$ is:
Correct Option: 1
Solution:
(1) The given circuit has two $10 k \Omega$ resistances in parallel, so we can reduce this parallel combination to a single equivalent resistance of $5 \mathrm{k} \Omega$.
Diode is in forward bias. So it will behave like a conducting wire.
$V_{A}-V_{B}=\frac{30}{5+10} \times 5=10 \mathrm{~V}$
