Find the charge on the capacitor $C = 2 \, \mu F$ in the given circuit in $\mu C$.

In the transient circuit shown,the time constant of the circuit is:

When a capacitor is connected to a battery,

In an experiment with a $C-R$ circuit,two identical capacitors,a resistor,and a $6V$ voltage source are used. For the parallel combination of capacitors,the time required for the voltage to reach half of its fully charged value is $10 \ s$. For the series combination,the time required for the voltage to reach half of its fully charged value is ...... $s$.

$A$ capacitor is connected to a $20\, V$ battery through a resistance of $10\, \Omega$. It is found that the potential difference across the capacitor rises to $2\, V$ in $1\, \mu s$. The capacitance of the capacitor is $....\, \mu F$. Given: $\ln(10/9) = 0.105$.

In the $RC$ circuit shown,the switch is closed at $t = 0$. Graphs showing the variation of potential $(V_R)$ across the resistor and potential $(V_C)$ across the capacitor are given. The time constant of the circuit is approximately equal to.....$ms$
