I can not seem to figure this out. My try so far:
- put C2 and C4 as C' by parallel
- put C' and C1 as C'' by series
- Finally, Put C'' and C3 and C5 as Ct by series
- find Qt by Qt=Ct*V
after finding the total Charge, i tried calculating backward toward V1 but could not manage to get the right answer. I found V1=99V which is wrong. P.S. The correct answer is 0.
Also i couldn't understand how a capacitor with 0 potential difference like.
