Homework Help: Impedance and Current

  1. May 30, 2014 #1
    I have solved it (:
    1. The problem statement, all variables and given/known data
    Ir=Impedance of a resistor = 330
    Ic=Impedance of a capacitor=318
    V= Sinusoidal Voltage = 240 V (RMS) is applied across the series combination.
    calculate the resulting current.

    2. Relevant equations
    Not sure

    3. The attempt at a solution
    I am really not sure how I would work out the resulting current.
    I = 250/sqrt(330^2+318^2)

    Should be 240/sqrt(330^2 + 318^2).
    Also, you have determined the magnitude of the current but not its phase.

    yes, sorry it's supposed to be 240 not 250. I am not sure what its phase is
