What is turn ratio formula?

@Kiran.
Turns ratio = sqrt (source resistance/load resistance).
Turns ratio = sqrt (source resistance/load resistance).

Thanks @Ravi.

To transfer max power turns ratio is (N2/N1)^2=ZL/Zin.

N2/N1=√R2/R1.

a^=(N1/N2)^2 = Z1/Z2 = R1/R2.
= N1/N2 = √(Zin/Zout),
= N1/N2 = √(320/20),
= N1/N2 = 4.
= N1/N2 = √(Zin/Zout),
= N1/N2 = √(320/20),
= N1/N2 = 4.
