Alternating current peak value

  1. Aug 30, 2015 #1
    1. The problem statement, all variables and given/known data
    If the peak values of current through inductor (L), capacitor (C) and resistor (R) in parallel AC circuit are 2mA, 3mA, and 5mA respectively, then the peak value of current delivered by the source in the same circuit will be

    2. Relevant equations

    3. The attempt at a solution
    i (R) = V/R or i (L) = V/wL or i (C) = VwC
    Using this, I found out R, wL and wC.
    Next, I found admittance.
    But the answer wasn't in any of the options.
    I don't know what to do next.

    Consider the phase relationships between the given currents. Taking the resistor current as reference, does the inductor current lead or lag? By what angle? How about the capacitor current?

    I was actually doing it right, just entering a number wrong repeatedly into my calculator.
    Yeah, I did.
    Thank you very much.
