For Equivalent Capacitance in series

##\frac{1}{C}##=##\frac{1}{C_1}##+##\frac{1}{C_2}##For Equivalent Capacitance in parallel

##C##=##C_1##+##C_2##...

##Q##=##C####v##

## The Attempt at a Solution

Equivalent capacitance between c and d (using series connection formula)

C1,C3 and C4 are in series

Ceq=2μF

this C eq and c2 are in parallel hence (using parallel connection formula)

Ceq'=8μc

This C'eq is in parallel with voltage hence it should have potential difference equal to 100 volts but it is wrong .I want to know why?
