Turns ratio, K = Np/Ns.

The Ans is 0.2, turn ration formula is N1/N2.

Here, it's asked for turns ratio, not transformation ratio.
Turns ratio is N1/N2.
2/N1 is the transformation ratio.
Turns ratio is N1/N2.
2/N1 is the transformation ratio.

@All.
How can apply N2 /N1 it is a transformation ratio no?
For turns ration we have N1/ N2 formula.
How can apply N2 /N1 it is a transformation ratio no?
For turns ration we have N1/ N2 formula.

Here, Everyone is presenting different logic. For the previous question, they applied v1/v2 = n1/n2 and here opposite formula, without logic
According to my point of view;
When it is step up.
V2/V1 = N2/N1.
And it is step down,
V1/V2 = N1/N2.
The question here is how to check whether it is step up or step down by just number Of turns?
If secondary has more turns, it means it is step up and vice versa for stepdown.

Turn ratio = N2/N1.
=2000/400 = 5 is the answer.
=2000/400 = 5 is the answer.

Turns ratio = N2/N1.
= 2000/400.
Ans = 5.
= 2000/400.
Ans = 5.

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.

Turns ratio = n1/n2 = 400/2000 = 0.2.
Transformation ratio = n2/n1.
Here turns ratio is asked not transformation ratio.
Transformation ratio = n2/n1.
Here turns ratio is asked not transformation ratio.

According to IEEE, the turn ratio is defined as the ratio of HV to LV. The definition says nothing about primary or secondary.
HV side will be the side with greater no. of turns and LV side will be the side with fewer no. of turns.
therefore, a=HV/LV.
i.e 2000/400=5.
HV side will be the side with greater no. of turns and LV side will be the side with fewer no. of turns.
