    A wire has a resistance of 12 ohm. It is bent in the form of equilateral triangle. The effective resistance between any two corners of the triangle is

    A)                    9 ohms

    B)                                      12 ohms

    C)                    6 ohms                            

    D)            8/3 ohms

    Correct Answer: D

    Solution :

                 As resistance µ Length  Resistance of each arm \[=\frac{12}{3}=4\Omega \]  Þ \[{{R}_{\text{effective}}}=\frac{4\times 8}{4+8}=\frac{8}{3}\Omega \]
