A inductor of 5.00 mH consists of a current of 7.50 mA flowing through it, whereas a 5.00 mF capacitor holds a charge of 7.50 mC.
(i) Determine the magnetic potential energy stored in the inductor?
(ii) Determine the electric potential energy stored in the capacitor?
(iii) The capacitance and inductance both are tripled. Then determine the ratio of the new potential energy in the inductor to the old, and of the new potential energy in the capacitor to the old?
(iv) The capacitance and inductance are returned to their original values, and the current and the capacitor's stored charge are both twice. Now, fin out the ratios of the new potential energies to the old?
