In a transformer, the transformation ratio is given by
$(K = \frac{{{V_2}}}{{{V_1}}} = \frac{{{I_1}}}{{{I_2}}})$
reciprocal of transformation ratio of a transformer is 21
The ratio of current in the secondary to primary $(\frac{{{I_2}}}{{{I_1}}} = \frac{1}{K} = 21)$
$(K = \frac{{{V_2}}}{{{V_1}}} = \frac{{{I_1}}}{{{I_2}}})$
reciprocal of transformation ratio of a transformer is 21
The ratio of current in the secondary to primary $(\frac{{{I_2}}}{{{I_1}}} = \frac{1}{K} = 21)$
