    If \[1\mu A\] current flows through a conductor when potential difference of 2V is applied across its ends, then the resistance of the conductor is:

    A) \[2\times {{10}^{6}}\Omega \]             

    B) \[3\times {{10}^{5}}\Omega \]

    C) \[1.5\times {{10}^{5}}\Omega \]                      

    D) \[5\times {{10}^{7}}\Omega \]

    Correct Answer: A

    Solution :

    (a) \[2\times {{10}^{6}}\Omega \] \[R=\frac{v}{l}=\frac{2}{{{10}^{-6}}}=2\times {{10}^{6}}\Omega \]
