Read the RL-transient class notes.


For the circuit shown,

  • R = 120 Ω
  • L = 470 mH

For the RL circuit, the source has been at an initial current value of Ii = 0 A for a long time.
At t = 0, the source current abruptly jumps to If = 1.2 mA.

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

Calculate the inductor current and voltage at t = 7.833 ms.
