Question

Circuit diagram has equal capacitance . The equivalent capacitance between point x & y is
A. 4 microF
B. 3micro F
C. 2 micro F
D. 6 micro F

Answer 1

No current flows through central branch.

So.

C1 and C2 in series implies,Cs=1/6+1/6=3microF

C3 and C4 in series implies,Cs=1/6+1/6=3microF

the resulting capacitance in parallel implies, 3+3=6microF
