R-L Circuit - Analysis deriving current at t=0, t=inf and t=0+. Integration and Laplace Methods.

In this video, I explore and analyse the the RL circuit deriving the equation for the current i(t) at t=0, t=inf and t=0+. I do this in two ways, first using integration to solve the diferential equation and then by using Laplace to solve the equation using algebra. For the step, impusle and frequency analysis, see the Part 5 video in this series.
