In the given circuit if point $C$ is connected to the earth and a potential of $+2000\,V$ is given to the point $A$ , the potential of $B$ is.....$V$

A

$1500$

B

$1000$

C

$500$

D

$400$

Solution

$ \mathrm{V}_{1}= \frac{15}{20} \times 2000=1500 \mathrm{\,volt} $

$ \mathrm{V}_{\mathrm{A}}-\mathrm{V}_{\mathrm{B}}=\mathrm{V}_{1} \Rightarrow 2000-\mathrm{V}_{\mathrm{B}}=1500$

$\mathrm{V}_{\mathrm{B}}=500 \mathrm{\,volt} $
