Turns ratio = N2/N1.
N2 = 2000.
N1 = 400.

T.R = N2/N1 = 2000/400 =5.

Teja said:   8 years ago
N1/N2 =400/2000 = 0.2.

Correct answer
N2/N1 = transformation ratio.

Answer is 0.2.
Turns ratio is n1/n2.
Transformation ratio is n2/n1.

Vijay said:   1 decade ago
N2/N1 is a transformation ratio.

Hence obviously 2000/400 = 5.

n2 = 2000.
n1 = 400.

We know,

k = n2/n1.
k = 2000/400.
k = 5.

What is the definition for transformer ratio and turns ratio?

Bibash said:   1 decade ago
This is all wrong turns ratio is N1/N2. So the answer is 0.2.

Chilufya said:   9 years ago
turn ratio = n1/n2
n1 = 400,
n2 = 2000,
.'. 400/2000 = 0.2.

Turns ratio N1/N2 & transformation ratio N2/N1.

Transformer ratio = K = N2/N1.
K = 2000%400 = 5.
