GROWTH OF CURRENT
![2245_r l circuit.png](https://www.expertsmind.com/../CMSImages/2245_r l circuit.png)
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![2140_r l circuit5.png](https://www.expertsmind.com/CMSImages/2140_r%20l%20circuit5.png)
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.
