RC Circuit + Pulse

  1. Apr 15, 2007 #1
    Hi, I have this problem to do for HW. I did what it asked for, or so I think. I think I may have made a mistake somewhere, it's telling me its not correct. Can you check it out?

    BTW, I have to use the step by step approach. I'm assuming my solution will be v(t) = K1 + K2 * e^(-t/RC).
    I then find V(infinity), V(0+) and V(0-), Rthevenin.

    V(0+) = V(0-) = 0. The input pulse does not charge the capacitor instantly. Only an impulse can do that.

    ah I see, we haven't hit impulses yet. Is the rest correct?

    You must recalculate the constants K1 and K2 for the correct initial condition.
    And you must calculate the response for t > 1s.
