The answer is wrong. "Transformation ratio" and "turns ratio" are one and the same thing, the formula is N1/N2 = V1/V2 = I2/I1.
The answer is k = 400/2000 = 0.2.
The answer is k = 400/2000 = 0.2.

Even I think the answer should be 0.2 as turns ratio indicate primary to secondary turns of transformer.
So here it is 400/2000 = 0.2.
If someone feels wrong please explain clearly.

When we find the single voltage and number of turn then we use Vp/Vs = Np/Ns.
But when we find the voltage or turn ratio it will reverse.
Voltage ratio = Vs/Vp.
Turn ratio = Ns/Np.
But when we find the voltage or turn ratio it will reverse.
Voltage ratio = Vs/Vp.
Turn ratio = Ns/Np.

Turns ratio (a) = N1/N2.
Transformation ratio (k) = V2/V1 =N2/N1 = I1/I2.
So answer should be 0.2.
Please don't interchange d meaning of. Tuns ratio and transformation ratio.
Transformation ratio (k) = V2/V1 =N2/N1 = I1/I2.

Please don't interchange d meaning of. Tuns ratio and transformation ratio.

1) Turns ratio in terms of number of turns is given by = higher number of turns/lower number of turns.
2) Turns ratio in terms of voltage is given by= low voltage/high voltage.
2) Turns ratio in terms of voltage is given by= low voltage/high voltage.

We know That turns Ratio is inversely proportional to the secondary wdg. & primary wdg.
Turns ratio (K) = Secondary wdg(N2) / Primary wdg (N1).
K = 2000/400.
= 5.
Turns ratio (K) = Secondary wdg(N2) / Primary wdg (N1).
K = 2000/400.
= 5.

Transformation Ratio = E2/E1 = v2/v1 = N2/N1 = k.
Turn Ratio = E1/E2 = V1/v2 = N1/N2 = 1/k.
So, Turn Ratio 1/k = N1/N2 = 400/2000 = 0.2.
So , the answer should be 0.2.
Turn Ratio = E1/E2 = V1/v2 = N1/N2 = 1/k.
So, Turn Ratio 1/k = N1/N2 = 400/2000 = 0.2.
So , the answer should be 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.

We know transformation ratio to be NP/NS=VP/VS=IS/IP.
Now how come the answer is 5 instead of 0.2.
Please can you come out clear with your formuler explanation?

According to IEEE "Turn ratio is higher voltage to lower voltage there isn't anything about primary and secondary voltage so high voltage divided by low voltage.
