Acoil has an inductance of 5 h and a resistance of 20 ω. if a dc voltage of 100 v is applied to the coil, find the energy stored in the coil when a steady maximum current has been reached

62.5 J

Explanation:

Given

Inductance(L)=5 H

resistance(R)

Voltage(V)=100 V

Current in L-R circuit is given by

and Power=i^2R+Li\frac{di}{dt}[/tex]

For Steady state i.e. at

Energy Stored is
