The energy stored in a capacitor is $W$. To double the charge on the plates of the capacitor,the additional work to be done is

$A$ capacitor is used to store $24 \, \text{watt-hour}$ of energy at $1200 \, \text{V}$. What should be the capacitance of the capacitor?

Four capacitors each of capacity $2 \mu F$ are connected as shown in the figure. If $V_{A}-V_{B}=10 \,V$,the energy stored in the system is:

If a capacitor of capacity $900 \mu F$ is charged to $100 \ V$ and its total energy is transferred to a capacitor of capacity $100 \mu F$, then its potential will be (in $V$)

Energy per unit volume for a capacitor having area $A$ and separation $d$ kept at potential difference $V$ is given by

If a $12 \ pF$ capacitor is connected to a $50 \ V$ battery,then the electrostatic energy stored in the capacitor is . . . . . . .
