What is equivalent capacitance of the network? Each capacitor has \[\text{1}\,\text{ }\!\!\mu\!\!\text{ F}\]capacitance:

A) \[\frac{1}{3}\]

B) \[2\mu F\]

C)  \[\frac{3}{2}\mu F\]

D)  \[3\mu F\]

Correct Answer: D

Solution :

 The given circuit can be rearranged as follows, it consists of three capacitors connected in parallel, hence equivalent resistance of the combination is \[C={{C}_{1}}+{{C}_{2}}+{{C}_{3}}\] Given, \[C=1+1+1=3\mu F\]
