The circuit shown in the figure consists of a charged capacitor of capacity

Question:

The circuit shown in the figure consists of a charged capacitor of capacity

$3 \mu \mathrm{F}$ and a charge of $30 \mu \mathrm{C}$. At time $\mathrm{t}=0$, when the key is closed, the

value of current flowing through the $5 \mathrm{M} \Omega$ resistor is ' $\mathrm{x}^{\prime} \mu-\mathrm{A}$. The value

of ' $x$ to the nearest integer is

Solution:

(2)

$\mathrm{i}_{0}=\frac{\mathrm{V}}{\mathrm{R}}=\frac{30 / 3}{5 \times 10^{6}}=2 \times 10^{-6}$

$\therefore$ Ans. $=2.00$
