We know that the energy stored in a capacitor is given by-W-Q22CNow- if the charge Q increases to 2Q-xA0-then the change in energy will be given by-W-x2032-2Q-22C-x21D2-4Q22C-4W

A capacitor of capacitance $C$ has charge $Q$ and stored energy $W$ . If the charge is increased to $2 Q$ , the stored energy would be:

$\frac{W}{4}$
$2 W$
$\frac{W}{2}$
$4 W$

We know that the energy stored in a capacitor is given by:
$W = \frac{Q^{2}}{2 C}$

Now, if the charge $Q$ increases to $2 Q$ ,
then the change in energy will be given by:

$W^{'} = \frac{(2 Q)^{2}}{2 C}$

$\Rightarrow \frac{4 Q^{2}}{2 C}$ $= 4 W$

A capacitor of capacitance C has charge Q and stored energy W. If the charge is increased to 2Q, the stored energy would be:W42WW24W

We know that the energy stored in a capacitor is given by:W=Q22CNow, if the charge Q increases to 2Q,then the change in energy will be given by:W′=(2Q)22C⇒4Q22C=4W
