Homework Help: Current in an inductor

  1. Nov 30, 2009 #1
    1. The problem statement, all variables and given/known data
    A current pulse is fed to the partial circuit shown in Figure P32.20. The current begins at zero, becomes 10.0A between t=0 and t= 200microseconds and then is zero once again. Determine the current in the inductor as a function of time.

    2. Relevant equations

    I= E/R(1-e^-t/T)

    3. The attempt at a solution

    not really sure what to do here or if that is even the right equation to use.

    Well, first you should show us Figure P32.20.

    sorry, I was going to copy and paste it but it wouldn't let me so I had to do it myself.
