Voltmeters $V_1$ and $V_2$ are connected in series across a DC line. $V_1$ reads $80 \mathrm{V}$ and has a $\mathrm{per} \mathrm{volt}$ resistance of $200 \mathrm{\Omega }$. $V_2$ has a total resistance of $32 \mathrm{k\Omega }$. The line voltage is

In the following circuit a capacitor is charged from $q=0$ to $q=2\mathrm{\mu C}$ after switching on the circuit find energy delivered by the cell.

When will this capacitor get maximum charge, and what will be values of maximum charge and current at that state of the circuit?

For the given arrangement shown in figure. The switch is closed at $t=0$ The time after which the current becomes $2.5\mathrm{\mu A}$ is

In the circuit shown in the figure

Capacitor $C_1$ is charged to a potential of $V.$ The current in the circuit just after the switch $S$ is closed
