The effective resistance between the points \[A\] and \[B\] in the figure is                                         [MP PET 1994]

A)                    \[5\,\Omega \]

B)                    \[2\,\Omega \]

C)                    \[3\,\Omega \]

D)                    \[4\,\Omega \]

Correct Answer: B

Solution :

             Given circuit is equivalent to So the equivalent resistance between points A and B is equal to \[R=\frac{6\times 3}{6+3}=2\Omega \]
