Read the RL-transient class notes.


For the circuit shown,

  • R = 100 Ω
  • L = 68 mH
  • IS = 12 mA

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 = 2.04 ms.
