Capacitors, how to find their cargo

  1. Nov 15, 2009 #1
    lets say we have these capasitors

    and we know Vab,C,C1,C2,C3 etc

    whats the method to find Q,Q1,Q2,Q3 etc ?

    thanks

    You Have Not Given values now

    Q=CVab
    Q1=CV1
    Q2=CV2
    Q3=CV3

    C'= 1/C2 + 1/C3 + 1/C4
    and C = 1/C'' + 1/C1 + 1/C5
    From This You will find Q = CVab

    lets say we have

    C1 = C5 = 3μF
    C2 = C3 = C4 = 2μF

    and Vab = 600 V.

    with these values i get

    C = 1 μF

    i think its correct but i cant find the correct answers using your method for the Q's

    so for example for Q1 it would be Q1 = 1*V1 but V1 = ?
