turns ratio =h.v(less current ,more turns)/l.v(more current, less turns)=2000/400=5

Here [always] turns ratio is H.V/L.V side

Transformation ratio = Vs/Vp = Es/Ep = Ns/Np = Ip/Is.
= Ns/Np = 2000/400 = 5.
= Ns/Np = 2000/400 = 5.

We know turn ratio = (turn on h. V) / (turn on l. V).
So,
Turn ratio = 2000/400.
Turn ratio = 5.
So,
Turn ratio = 2000/400.
Turn ratio = 5.

so much confusion in the formula
Turn ratio is N1/N2 or N2/N1.
you have tried both the formula in two questions given here.

But actually the formula for turns ratio is N1/N2 so the answer will be 0.2.
Please reply why all taken it as N2/N1.

Primary turns(N1)=400
Secondary turns(N2)=2000
Turn Ratio(K)=N2/N1
=>2000/400=5.
This Is Ans
Secondary turns(N2)=2000
Turn Ratio(K)=N2/N1
=>2000/400=5.
This Is Ans

TURN RATIO FORMULA=SECONDARY TURNS(N2)/PRIMARY TURNS(N1).
SO, VALUE OF N2=2000 AND VALUE OF N1=400.
=>N2/N1
=>2000/400=5. THIS IS ANS.

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.

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