ആശയം:

ഒരു ട്രാൻസ്‌ഫോർമറിന്റെ ടേൺ റേഷ്യോ (n ചുറ്റുകളുടെ അനുപാതം) ഇങ്ങനെ നൽകിയിരിക്കുന്നു

\(n = \frac{{{N_1}}}{{{N_2}}} = \frac{{{E_1}}}{{{E_2}}} = \frac{{{I_2}}}{{{I_1}}}\)

ഇവിടെ,

N1 = പ്രാഥമിക വശത്തെ ചുറ്റുകളുടെ എണ്ണം 

N2 = ദ്വിതീയ വശത്തെ ചുറ്റുകളുടെ എണ്ണം 

E1 = പ്രാഥമിക വശ വോൾട്ടേജ് 

E2 = ദ്വിതീയ വശ വോൾട്ടേജ് 

I1 = പ്രാഥമിക കറന്റ് 

I2 = ദ്വിതീയ കറന്റ് 

കണക്കുകൂട്ടൽ:

നൽകിയത്-

n = 2, E2 = 100 V

∴ \(2 = \frac{{{E_1}}}{{{100}}} \)

E1 = 200 V
