When a voltage of 220 V is applied to a coil with resistance of 50Ω, produces 5mWb of flux. If the coil has 1000 turns, find inductance of coil and energy stored in the magnetic field.

I=V/R=220/50=4.4
Flux=n L(inductance) ×I
L=5/4.4×1000
L=1.13×10^-3
E=1/2LI²
E=0.0218/2
E=0.0109J
I hope this helps ( ╹▽╹ )
