  • question_answer
    Three resistors each of \[4\,\Omega \] are connected together to form a network. The equivalent resistance of the network cannot be

    A)                    \[1.33\,\Omega \]

    B)                                      \[3.0\,\Omega \]

    C)                    \[6.0\,\Omega \]

    D)                                      \[12.0\,\Omega \]

    Correct Answer: B

    Solution :

                 If all are in series then \[{{R}_{eq}}=12\,\Omega \] If all are in parallel then \[{{R}_{eq}}=\frac{4}{3}\Omega =1.33\,\Omega \] If two are in series then parallel with third, \[{{R}_{eq}}=\frac{8}{3}=2.6\,\Omega \] If two are in parallel then series with third, \[{{R}_{eq}}=6\,\Omega \]
