If $E$ is the electric field intensity of an electrostatic field, then the electrostatic energy density is proportional to
$E$
${E^2}$
$1/{E^2}$
${E^3}$
A $10\,pF$ capacitor is connected to a $50 \,V$ battery. How much electrostatic energy is stored in the capacitor
A $10\, micro-farad$ capacitor is charged to $500\, V$ and then its plates are joined together through a resistance of $10\, ohm$. The heat produced in the resistance is........$J$
In the figure shown, after the switch $‘S’$ is turned from position $‘A’$ to position $‘B’$, the energy dissipated in the circuit in terms of capacitance $‘C’$ and total charge $‘Q’$ is
How does a capacitor store energy ? And obtain the formula for the energy stored in the capacitor ?
