Question

In the given circuit, find potential at point ' $O$ '

• A. $\frac{4V}{11}$
• B. $\frac{3V}{11}$
• C. $\frac{9V}{11}$
• D. None of these

Answer 1

Answer: (A)

$(X-0)C+(X-0)C+(X-V)C+(X-Y)C=0$
$4X-Y=V\dots (1)$

$(Y-0)C+(Y-X)C+(Y-V)C=0$
$3Y-X=V\dots (2)$
On solving
$11X=4V$
$X=\frac{4V}{11}$
