Here frequency not be changed. Otherwise it just transmitted.

In transformers we use the 50hz, because of how much of load is given it will be operated at the same frequency so that we use the constant.

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

Somebody told turns ratio equal to sqrt of the load. Is it correct or not ?

Turns ratio=a(n2/n1a)
Therefor R2=a^2*R1
a^2=R2/R1=4
a=2
Therefor R2=a^2*R1
a^2=R2/R1=4
a=2

What kallan said is right and less time consuming as wel as easy to remember.

As in a transformer input power = output power i.e. energy is transformed, v1^2 / z1 = v2^2 /z2. hence turns ratio = sqrt(z2/z1)

I am satisfy with Pruthiwi Raj answer.

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

sqrt(v1/v2)=r1/r2;
so,k=2
so,k=2
