How can we say the answer is 5 ? Because in this problem you are mentioned primay is 400,secondary is 2000.
So my answer is turns ratio is 0.2 .
Here somebody said the answer is 5. They mentioned clearly in the problem primary turns is 400, secondary turns is 2000.
Please tell the reason clearly.

Primary turns (n1) =400.
Secandary turns (n2) =2000.
Turns ratio (k) = n2/n1.
=2000/400.
Ans=5.
Secandary turns (n2) =2000.
Turns ratio (k) = n2/n1.
=2000/400.
Ans=5.

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

trasformation ratio,k=N2/N1
turns ratio=1/k= N1/N2
turns ratio=1/k= N1/N2

Turn ratio =N2/N1 or V2/V1.
As given
N2=2000
N1=400
so-
2000/400 = 5 ans.
As given
N2=2000
N1=400
so-
2000/400 = 5 ans.

Transformer ratio is always mention in the form of N1/N2 so I suppose that the answer should be 0.2 because N1 showing primery & N2 is secondary. If answer is 5 than 2000 should be primary & 400 should be secondary.

n=v2/v1
n=2000/400
n=5
n=2000/400
n=5

I think its wrong because turns ratio is different from transformation ratio transformation ratio k=1/n=V2/V1=I1/I2

We know that:- Turn ratio=N2/N1;
HERE N2=2000;
N1=400;
T.R=2000/400=5
HERE N2=2000;
N1=400;
T.R=2000/400=5

Turn ratio k=n2/n1=e2/e1=i1/i2
n2/n1=2000/400=5
n2/n1=2000/400=5
