हिन्दीIn an ideal transformer, the turns ratio is \( \frac{N_p}{N_s} = \frac{1}{2} \). The ratio \( V_s : V_p \) is equal to (the symbols carry their usual meaning):
Correct answer · Option 4
2 : 1
Explanation
For an ideal transformer, \( \frac{V_s}{V_p} = \frac{N_s}{N_p} \). Given \( \frac{N_p}{N_s} = \frac{1}{2} \), we have \( \frac{V_s}{V_p} = \frac{2}{1} \), which gives \( V_s : V_p = 2 : 1 \).
