    Five resistances are connected as shown in the figure. The effective resistance between points A and B is

    A)  \[\frac{10}{3}\Omega \]            

    B)  \[\frac{10}{17}\Omega \]

    C)  \[40\Omega \]

    D)  \[45\Omega \]

    Correct Answer: A

    Solution :

    It is a parallel combination of three resistances, each of \[10\Omega \]. \[\therefore \] The effective resistance between points A and B. \[\frac{1}{R}=\frac{1}{10}+\frac{1}{10}+\frac{1}{10}\] or \[R=\frac{10}{3}\Omega \]
