Read the RL-transient class notes.
For the circuit shown,
- R = 680 Ω
- L = 3.3 H
- VS = 20 V
For the RL circuit, the switch has been open for a long time, and it closes abruptly at t = 0.
Prior to the switch closing the inductor current was zero.
Determine the expression for the inductor current as a function of time, for t > 0.
