A capacitor of capacitance $C$ is charged to potential difference $V_0$. Now this capacitor is connected to an ideal inductor. When $25\%$ of energy of capacitor is transferred to inductor then at that time what will be potential difference across capacitor
$\frac {V_0}{2}$
$\frac {\sqrt 3}{2} \,\,V_0$
$\frac {V_0}{4}$
$\frac {V_0}{\sqrt 3 }$
A $5.0\, \mu F$ capacitor is charged to a potential difference $800\, V$ and discharged through a conductor. The energy(in $J$) given to a conductor during the discharge is
In a uniform electric field, a cube of side $1\ cm$ is placed. The total energy stored in the cube is $8.85\ μJ$ . The electric field is parallel to four of the faces of the cube. The electric flux through any one of the remaining two faces is
As in figure shown, if a capacitor $C$ is charged by connecting it with resistance $R$, then energy is given by the battery will be
A capacitor of capacity $C$ is connected with a battery of potential $V$ in parallel. The distance between its plates is reduced to half at once, assuming that the charge remains the same. Then to charge the capacitance upto the potential $V$ again, the energy given by the battery will be
How does a capacitor store energy ? And obtain the formula for the energy stored in the capacitor ?
