Question
Rate of increment of energy in an inductor with time in series LR circuit getting charge with battery of e.m.f. E is best represented by: [inductor has initially zero current]
Options
A.
B.
C.
D.
Solution
Rate of increment of energy in inductor = 
= 
= Li 
Current in the inductor at time t is:
i = i0
and 
= 
∴
= 
= 0 at t = 0 and t = ∞
Hence E is best represented by :
= = Li Current in the inductor at time t is:
i = i0
and = ∴
= = 0 at t = 0 and t = ∞Hence E is best represented by :
