The charge stored by the capacitor $C$ in the given circuit in the steady state is . . . . . . $\mu C$.

$A$ capacitor is charged to a potential difference of $100\, V$ and then connected across a resistor. The potential difference across the capacitor decays exponentially with time. After $1\, s$,the potential difference across the capacitor plates is $80\, V$. What is the fractional loss of the stored energy?

What will be the current through the $200 \Omega$ resistor in the given circuit, a long time after the switch $K$ is closed?

At time $t=0$,a battery of $10 \ V$ is connected across points $A$ and $B$ in the given circuit. If the capacitors have no charge initially,at what time (in seconds) does the voltage across them become $4 \ V$? [Take $\ln 5=1.6, \ln 3=1.1$]

For the given input voltage waveform $V_{\text{in}}(t)$,the output voltage waveform $V_0(t)$ across the capacitor is correctly depicted by:

$A$ capacitor of $4\, \mu F$ is connected to a $15\, V$ supply through a $1\, M\Omega$ resistance. The time taken by the capacitor to charge up to $63.2\%$ of its final charge will be......$s$.
