Read the RL-transient class notes.
For the circuit shown,
- R = 220 Ω
- L = 1 mH
- IS = 1.9 A
For the RL circuit, the switch has been closed for a long time, and it opens abruptly at t = 0.
Determine the expression for the inductor current as a function of time, for t > 0.
Calculate the inductor current and voltage at t = 20.45 μs.
