The capacitance between the points A and B in the given circuit will be [AMU (Med.) 1999; MH CET 1999; Pb. PET 2002; BCECE 2005]

A)            1\[\mu \,F\]

B)            2\[\mu \,F\]

C)            3\[\mu \,F\]

D)            4\[\mu \,F\]

Correct Answer: A

Solution :

                   \[\frac{1}{{{C}_{AB}}}=\frac{1}{3}+\frac{1}{3}+\frac{1}{3}=1\] Þ \[{{C}_{AB}}=1\,\mu F\]
