GROWTH OF CURRENT
When switch is on at t = 0. Then current flows from 0 to I. And self inductor opposes the grow of current
Ldl/dt = Potential energy difference across inductor = εe-Rt/L
I
At t = 0 => potential energy difference across inductor = e
At t → ∞ => potential energy difference across inductor = 0.

So inductor will function like plane wire.
Take a graph betn I and time.

Take a graph betn potential difference across
Inductor and time
