What is the formula to determine the transformation ratio ‘K'?
1
\(K = \frac{{{N_2}}}{{{N_1}}} = \frac{{{E_2}}}{{{E_1}}} = \frac{{{I_2}}}{{{I_1}}}\)
2
\(K = \frac{{{N_1}}}{{{E_1}}} = \frac{{{N_2}}}{{{E_2}}} = \frac{{{I_2}}}{{{I_1}}}\)
3
\(K = \frac{{{N_2}}}{{{I_1}}} = \frac{{{E_2}}}{{{N_1}}} = \frac{{{I_2}}}{{{E_1}}}\)
4
\(K = \frac{{{N_2}}}{{{N_1}}} = \frac{{{E_2}}}{{{E_1}}} = \frac{{{I_1}}}{{{I_2}}}\)
