Read the RL-transient class notes.


For the circuit shown,

  • R1 = 1.8 kΩ
  • R2 = 2.7 kΩ
  • R3 = 2.7 kΩ
  • L = 470 mH

For the RL circuit, the source has been at an initial voltage value of Vi = -9 V for a long time.
At t = 0, the source voltage abruptly jumps to Vf = 18 V.

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