A) \[4.62\times {{10}^{-2}}\]
B) \[2.03\times {{10}^{-2}}\]
C) \[3.16\times {{10}^{-2}}\]
D) \[5.62\times {{10}^{-2}}\]
Correct Answer: C
Solution :
For primary & secondary circuit, \[{{V}_{s}}{{l}_{s}}={{V}_{p}}{{l}_{p}}\]where symbols have their usual meaning. \[\Rightarrow \]\[\frac{V_{s}^{2}}{{{Z}_{5}}}=\frac{V_{p}^{2}}{{{Z}_{p}}}\]\[\Rightarrow \]\[\frac{V_{s}^{2}}{{{Z}_{5}}}=\sqrt{\frac{Z_{s}^{{}}}{{{Z}_{p}}}}=\sqrt{\frac{10}{{{10}^{4}}}}=\frac{\sqrt{10}}{100}\] So turns ratio, \[\frac{V_{s}^{{}}}{{{V}_{p}}}=\]turn ratio \[=\frac{\sqrt{10}}{100}=3.16\times {{10}^{-2}}\]
