Turn ratio (n) of a transformer is given as
\(n = \frac{{{N_1}}}{{{N_2}}} = \frac{{{E_1}}}{{{E_2}}} = \frac{{{I_2}}}{{{I_1}}}\)
Where,
N1 = Number of turns across primary side
N2 = Number of turns across secondary side
E1 = Primary side voltage
E2 = Secondary side voltage
I1 = Primary current
I2 = Secondary current
Calculation:
Given-
n = 2, E2 = 100 V
∴ \(2 = \frac{{{E_1}}}{{{100}}} \)
E1 = 200 V
