[UPSC CSE 2020] Electrostatics and Magnetostatics (Q69, 15M)

Describe the oscillations of electric and magnetic fields in an ideal LC circuit. The applied voltage phasor in a circuit is (4+3i) volt and resulting current phasor is (3+4i) ampere. Draw the phasor diagram. Determine the impedance of the circuit and indicate whether it is inductive or capacitive in nature. Also find the power dissipation in the circuit.
