What is the actual formula for turns ratio is it K=N1/N2 OR K=N2/N1 & what is transformation ration?

v1xi1=v2i2
v1=cxn1
v2=cxn2
i1=v1/r1
i2=v2/r2
so
(n2/n1)2=(r2/r1)
Hence turns ratio n2/n1=root(4)=2
v1=cxn1
v2=cxn2
i1=v1/r1
i2=v2/r2
so
(n2/n1)2=(r2/r1)
Hence turns ratio n2/n1=root(4)=2

Turns Ratio = sqrt.(r2/r1)
= sqrt (320/80)
= sqrt (4)
= 2
= sqrt (320/80)
= sqrt (4)
= 2

Here the value is in ohms.
i.e resistive
It will be more in winding.
n2/n1 = k,
320/80 = k,
= 4.

v2/v1 = i1/i2.
= v1/r1*r2/v2.
(v2/v1)^2 = r2/r1.
(k)^2 = r2/r1.
k^2 = 320/80.
k^2 = 4 .
k = 2.
= v1/r1*r2/v2.
(v2/v1)^2 = r2/r1.
(k)^2 = r2/r1.
k^2 = 320/80.
k^2 = 4 .
k = 2.

No! @Hanumantha Hk.
The correct law is : vs/sp = NS/NP = IP/IS.
Please, revise once again.

R(hv) = K^2*R(lv).
[v2/v1 = k,i2*r2/i1*r1 = k, R(hv)/R(lv) = k^2; k = 2; r2/r1 = k^2].
[v2/v1 = k,i2*r2/i1*r1 = k, R(hv)/R(lv) = k^2; k = 2; r2/r1 = k^2].

If the above statment true that turn ratio is equal to load /source then answer comes 2.

Can anyone give formula derivation for showing turns ratio in terms of resistance?
Rakesh said:

Turn ratio = √(R2/R1).
= √(360/80),
= √4,
= 2.
= √(360/80),
= √4,
= 2.
