Circuits Question - Voltage and current in an inductor circuit

    Circuits Question -- Voltage and current in an inductor circuit

    1. The problem statement, all variables and given/known data

    See Attached

    2. Relevant equations



    3. The attempt at a solution

    I found Zeq and there are exactly 2 Amps going into it. I'm not sure what to do from here.

    [itex]Z_{eq} = \frac{<(arctan(\frac{R}{ωL}))}{ω^{2}L^{2}+R^{2}}[/itex]

    I'm not sure what to do from here, thanks for any help.

    Re: Circuits Question

    Ok so because this is DC

    ω = 2∏f

    but f= 0

    so

    [itex]Z_{eq} = \frac{j}{R^{2}}[/itex]

    Where do I go from here?

    vL(t) = 120e-2500t

    iL(t) = 2 + 6e-2500t
