Question

Seven capacitors, a switch S and a source of emf are connected as shown in the figure. Initially, S is open and all capacitors are uncharged. After S is closed and steady state is attained, the potential difference in volt across the plates of the capacitor A is

• A. 12
• B. 15
• C. 17
• D. 19

Answer 1

The correct option is A 12

$\therefore Q=59\times \frac{84}{59}=84\mu c$

$\therefore voltageacross7\mu F=\frac{84}{7}V=12V$

Hence,

option $\left(A\right)$ is correct answer.
