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.

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.

Secondary turns divided by the primary turns gives turn ratio.
N2/N1 = turn ratio.
2000/400 = 5.
N2/N1 = turn ratio.
2000/400 = 5.

Turns ratio.
I think n1/n2 because transformation ratio is n2/n1 once you cross I agree @Jyothi.

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

Answer is 0.2 only or else Tell me the difference between turns ratio and transformation ratio.

As we know that the transformer turn ratio N2/N1 so that 2000/400 = 5 so answer is C correct.

I agree @Rajkumar.
Second thing is that they can never be fractional it is always integral.

I think the answer must be 0.2 as we N1=400 and N2=2000 so the ration should be 1/5 not 5/1.

Answer must be 0.2.
Transform ratio (N2/N1 = V2/V1 = I1/I2), turn ratio different (N1/N2).
Transform ratio (N2/N1 = V2/V1 = I1/I2), turn ratio different (N1/N2).
