Read the RL-transient class notes.
For the circuit shown,
- R = 680 Ω
- L = 68 mH
For the RL circuit, the source has been at an initial current value of Ii = 0.14 A for a long time.
At t = 0, the source current abruptly drops to If = -50 mA.
Determine the expression for the inductor current as a function of time, for t > 0.
Calculate the time when the inductor current will be equal to 45 mA and calculate the inductor voltage at that time.
