Homework Help: Find i(t)

  1. Jun 16, 2013 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations
    impedence diagram, XL = ωL

    3. The attempt at a solution

    Ok i got XL = 47 ohm
    Then my phase angle is 88.8 degree.

    Then to find i(t) i have to add that angle to the function right?

    That's not quite right.

    If you show your work maybe we can help find where things went wrong.

    Convert the inductance to an impedance and add it to the resistance. You now have an equivalent circuit with the voltage drop across the impedance given. Use Ohm's law to find the current.

    Remember ω = 2*pi*f
