turn ratio = n1/n2
n1 = 400,
n2 = 2000,
.'. 400/2000 = 0.2.

Turns ratio k = E2/E1,

= 2000/400 = 5.

Why not primary/secondary i.e. 400/2000?

AYYUBKHAN said:   9 years ago
Transformer primary side = 400turns.
Transformer secondary side = 2000 turns.

Calculate transformer ratio?
Transformer ratio(k) = n2/n1,
= 2000/400.
Transformer ratio(k) = 5.

Turn ratio =N1/N2 and transformation ratio=N2/N1.
Turn ratio=400/2000 = 0.2.

Turns ratio and transformation ratio both are different. So this answer is wrong.

Ashok kumar said:   9 years ago
Turns ratio is N1/N2.
Transformation ratio is N2/N1.
So, the answer is 0.2.

Turns Ratio = Np/Ns.
It depends upon how the winding is connected.
In the given question,
Np = 400.
Ns = 2000.

Hence, Np/Ns= 400/2000 = 0.2.
So the turn Ratio is 0.2.

Kirthi Arora said:   9 years ago
Turn ratio is define as ratio of turns of wire in the primary winding to its secondary winding. So Turn ratio = Np/Ns => 400/2000 = 0.2.

As per my knowledge turn ratio= n1/n2.
Transformation ratio = n2/n1.

So, as per formula the ans will be 0.2.
