    Hi,

    I need help on this question. This is actually my working. I am certain i got my AC wrong. I1.
    I seldom do AC source.
    DC I should be correct.
    Could anybody help?

    Question is Find the steady current IL(T)
    The answer is -2 +0.707 cos (10t - 45degrees) Ampere
    I believe the 0.707 is the RMS. But cant figure anything out.

    Thanks.

    is the 3 a current source ac?
    first find out the frequency of voltage source comparing 10t=wt
    and frequency = w/2pi
    and then find the reactances.
    post back if u need any further help.
