Question

In the figure, given $C_1=3\mu F,C_2=5\mu F,C_3=9\mu F$ and $C_4=13\mu F$. What is the potential difference between points $A$ and $B$ ?

• A. $13V$
• B. $9V$
• C. $0V$
• D. $11V$

Answer 1

The correct option is A $13V$

Voltage difference across $C_3$ and $C_4$ is $22V$.
Now this potential will be divided between $C_3$ and $C_4$.
$V_3=\frac{C_{4}V}{C_3+C_4}=\frac{13\times 22}{9+13}=13V$

Hence, potential difference across A and B will be $13V$.
