The Source-Free RC Circuit
Consider the series connection of a resistor and an inductor, as shown in the figure in the left, we will assume to be the current i(t) through the inductor. We select the inductor current as the response in order to take advantage of the idea that the inductor current cannot change instantaneously. At t=0 we assume that the inductor has an initial current Io or |
The Key to Working with a Source-free RL Circuit Is to Find:
1. The initial current i(0) = Io through the inductor.
2. The time constant t (tau) of the circuit.
1. The initial current i(0) = Io through the inductor.
2. The time constant t (tau) of the circuit.
