Five capacitors of \[10\mu F\]capacity each are connected to a d.c. potential of \[100\ volts\] as shown in the adjoining figure. The equivalent capacitance between the points \[A\]and\[B\] will be equal to     [CPMT 1986, 88; MP PMT 1999]

A)                    \[40\mu F\]

B)                    \[20\mu F\]

C)                    \[30\mu F\]

D)                    \[10\mu F\]

Correct Answer: D

Solution :

           In the given system, no current will flow through the branch CD so it can be removed Effective capacitance of the system \[=5+5=10\mu F\]
