Read the RL-transient class notes.


For the circuit shown,

  • R = 82 Ω
  • L = 68 mH

For the RL circuit, the source has been at an initial current value of Ii = 100 mA for a long time.
At t = 0, the source current abruptly drops to If = 0 A.

Determine the expression for the inductor current as a function of time, for t > 0.

Calculate the inductor current and voltage at t = 4.146 ms.
