Four capacitors are connected in a circuit as shown in the figure. The effective capacitance in \[\mu F\]between points A and B will be                 [MP PET 1996; Pb. PMT 2001; DPMT 2003]

A)                                                      \[\frac{28}{9}\]

B)                    4

C)                    5

D)                    18

Correct Answer: C

Solution :

                   The circuit can be rearranged as Net capacitance between \[AB=\frac{4\times 12}{4+12}+2=5\,\mu F\]
