Vedclass · Answer

(D) When a charged capacitor is connected in parallel with an inductor (coil),it forms an $LC$ circuit.Initially,the energy is stored in the electric field of the capacitor as $U_E = \frac{1}{2} \frac{Q^2}{C}$.As the capacitor discharges,current flows through the coil,creating a magnetic field and storing energy as $U_B = \frac{1}{2} L I^2$.Due to the exchange of energy between the electric field of the capacitor and the magnetic field of the inductor,the charge on the capacitor and the current in the circuit oscillate sinusoidally.In an ideal $LC$ circuit (assuming no resistance),these oscillations continue indefinitely without damping.

$A$ capacitor is fully charged with a battery. Then the battery is removed and a coil is connected with the capacitor in parallel. How does the current vary?
