    An AC source has an internal resistance of \[2.03\times {{10}^{-2}}\]. Calculate the turn ratio of a transformer so as to match the source to a load of resistance \[3.16\times {{10}^{-2}}\].

    A)  \[5.62\text{ }\times {{10}^{-2}}\]            

    B)  \[\lambda \]

    C)  \[1A\]                 

    D)  \[2A\]

    Correct Answer: C

    Solution :

                    We know, power \[={{E}_{s}}\,\,{{l}_{s}}\,\,={{E}_{p}}{{l}_{p}}\] \[{{E}_{s}}\left( \frac{{{E}_{s}}}{{{Z}_{s}}} \right)={{E}_{p}}\left( \frac{{{E}_{p}}}{{{Z}_{p}}} \right)\] \[\frac{{{E}_{s}}}{{{E}_{p}}}=\sqrt{\frac{{{Z}_{s}}}{{{Z}_{b}}}}=\sqrt{\frac{10}{10000}}\] \[\frac{{{E}_{s}}}{{{E}_{p}}}=\frac{\sqrt{10}}{100}=3.16\times {{10}^{-2}}\]
