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
urduworld
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 = ?
