Answer:62.5 J
Explanation:
Given
Inductance(L)=5 H
resistance(R)
Voltage(V)=100 V

Current in L-R circuit is given by
![I=I_0\left [ 1-e^{-\frac{Rt}{L}}\right ]](https://tex.z-dn.net/?f=I%3DI_0%5Cleft%20%5B%201-e%5E%7B-%5Cfrac%7BRt%7D%7BL%7D%7D%5Cright%20%5D)
and Power=i^2R+Li\frac{di}{dt}[/tex]
For Steady state i.e. at

Energy Stored is 

Answer:Transformer
Explanation:All the other devices generate their own electricity apart from power line and Transformer, power line just carries electricity. A transformer can be used to step up or step down voltages from a source.
