Answer:
a. The stored electric field energy can be greater than the stored magnetic field energy.
b. As the capacitor is discharging, the current is increasing.
d. The stored electric field energy can be less than the stored magnetic field energy.
e. The stored electric field energy can be equal to the stored magnetic field energy.
Explanation:
We know that total energy of capacitor and inductor system given as
L=Inductance ,I =current
C=Capacitance ,V=Voltage
The total energy of the system will be remain conserve.If energy in the inductor increases then the energy in the capacitor will decrease and vice -versa.
The values of stored energy in the capacitor and inductor can be equal ,greater or less than to each other.But the summation will be constant always.
Therefore the following option are correct
a ,b , d , e
