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

If $E$ is the electric field intensity of an electrostatic field, then the electrostatic energy density is proportional to

In which of the following stores maximum energy ?

In a charged capacitor, the energy resides

A $40$ $\mu F$ capacitor in a defibrillator is charged to $3000\,V$. The energy stored in the capacitor is sent through the patient during a pulse of duration $2\,ms$. The power delivered to the patient is……$kW$
