Parallel RC Circuit Problem

    Parallel RC Circuit Problem!!!!!!!!!!!!!

    Hey ive been working on this circuit for hours and cant figure out 1 value.
    This is exactly what was given to me on the page so i have no other information lol.

    All that was written was:

    find the values of Zt,It,I1,I2,Vc1

    Ive found all the other values which are

    Zt = 1.2 k angle -10.93
    It = 8.28 mA angle 10.93
    I1 = 8.13 mA angle 0
    I2 = 1.57 mA angle 90
    Vc1 i get 31.8 v angle -90 but the given answer is 5v and 0

    An explanation y it is that value would be appreciated

    Well personally I would NOT call you dumbwit or any other name , but I am afraid he is correct in that I am not sure how anyone can understand your question

    Hi DethRose,
    The capacitors are equal in size and form a simple voltage divider across the source. Regardless of the current through the capacitors, the voltage across each capacitor must logically be half of the source voltage ... 5v @ 0degrees.

    =V_s\frac{j\omega C1}{j\omega C1+j\omega C2}

    (it seems your other respondents have no imagination)
