    Hi, for this question, used the equation i(t) = i(∞) + [i(t=0) - i(∞)]*e(Lt/R)
    with i(∞) = 0 to find the current at time = 70 ms

    Then tried to solve for V0(t) by adding voltage cross R2 and the inductor.
    But I can't get the answer -7.2206.

    Any help would be much appreciated :)

    How can we possibly determine where you went wrong when you haven't shown us your work or even so much as what answer you did get.

    We are not mind readers and we will not do YOUR homework for you.
