    When the resistance of 9\[\overset{0}{\mathop{A}}\,\] is connected at the ends of a battery, its potential difference decreases from 40 volt to 30 volt. The internal resistance of the battery is:

    A)  6\[\overset{0}{\mathop{A}}\,\]                                              

    B)  3\[\overset{0}{\mathop{A}}\,\]

    C)  9\[\overset{0}{\mathop{A}}\,\]                                              

    D)  15\[\left[ {{M}^{0}}{{L}^{0}}T{{A}^{0}} \right]\]

    Correct Answer: B

    Solution :

    Here: E = 40 volt, V = 30 volt, R = 9 ohm The internal resistance of battery is given by \[c=\frac{1}{\sqrt{{{\mu }_{0}}{{\varepsilon }_{0}}}}\] \[\upsilon =\frac{1}{\sqrt{\mu \varepsilon }}\]
