The equivalent resistance of the arrangement of resistances shown in adjoining figure between the points A and B is                                                               [CPMT 1990; BVP 2003]

A)                                                      6 ohm

B)                    8 ohm

C)                    16 ohm

D)                    24 ohm

Correct Answer: B

Solution :

             \[{{R}_{AB}}=\frac{24\times 12}{(24+12)}=8\Omega \]
