V1/V2 = N1/N2 = E1/E2 = a.
Where 'a' is turns ratio.
400/2000 = 0.2.
Where 'a' is turns ratio.
400/2000 = 0.2.

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).

Hi friends this answer is wrong because,
Turn ratio = N1/N2.
= 400/2000 = 0.2.
Turn ratio = N1/N2.
= 400/2000 = 0.2.

Hi guys this is wrong right.
Because N1/N2 = 'n' this is turns ratio.
So answer is = 0.2. How it comes 5?
Transformer ratio is N2/N1 = V2/V1 = I1/I2 = K this is transformer ratio.
In the question they are clearly ask Turns ratio. Then how it comes this answer. Please due to that am confused in one of my Exam. So please tell clearly any one.
NI/N2 = 'n' turns ratio.
N2/N1 = K, this is transformer ratio.
Because N1/N2 = 'n' this is turns ratio.
So answer is = 0.2. How it comes 5?
Transformer ratio is N2/N1 = V2/V1 = I1/I2 = K this is transformer ratio.

We know,
Ratio = n2/n1 [k = n2/n1].
Than, k = 2000/400.
k = 5.
So, ratio is 5.
Ratio = n2/n1 [k = n2/n1].
Than, k = 2000/400.
k = 5.
So, ratio is 5.

Turn ratio = n = vp/vs.
400/2000 = 0.2.
400/2000 = 0.2.

n2 = 2000.
n1 = 400.
We know,
k = n2/n1.
k = 2000/400.
k = 5.
n1 = 400.
We know,
k = n2/n1.
k = 2000/400.
k = 5.

N2/N1 = 2000/400 = 5/1.
So answer is 5.
So answer is 5.

Turns ratio k = n2/n1.
n2 = 2000, n1 = 400 now k = 2000/400.
So k = 5.
n2 = 2000, n1 = 400 now k = 2000/400.
So k = 5.

No.of turns in the primary (N1) = 400.
No.of turns in the secondary(N2) = 2000.
Turns ratio = N2/N1 = 2000/400 = 5.
No.of turns in the secondary(N2) = 2000.
Turns ratio = N2/N1 = 2000/400 = 5.
