Q. Calculate the potential difference across the capacitor in the circuit (in Volts). (Approximate the answer to the nearest integer)
Question

NTA AbhyasNTA Abhyas 2022

Solution:

Solution
Net current at point $x=0.$
$\therefore \frac{0 - x}{10}+\frac{8 - x}{4}+\frac{0 - \left(x + 2\right)}{5}=0\Rightarrow x=2.909$
Potential across capacitor $\Rightarrow \left[\left(x + 2\right) - 8\right]=-3.09\simeq 3$
