Turn ratio will be proportion to square root of load.

Turns ratio2 = load impedance/source impedance

=2

v1 I1=v2 I2
v1*v1/r1=v2*v2/r2
sq of (v1/v2)=r2/r1
sq of (1/k)=r2/r1=4
1/k=2------this is turns ratio
k=1/2-----this is transformation ratio
bcoz--n2/n1==transformation ratio
and
n1/n2==turns ratio

Jegan said:   1 decade ago
sq of(v1/v2)=r1/r2

Rajneesh said:   1 decade ago
Turns ratio=(n2/n1)^1/2

Here r1=80ohm, r2=320 ohm
we know v2/v1=i1/i2
v2/v1=v1/r1*r2/v2
=> k=(v1/v2)*(r2/r1)
=> k=1/k*(320/80)
=>K sq=4
k=2
Ans=2

N2/N1=320/80=4

turns ratio= sq rt(n2/n1)=2

I wants that why the frequency is constant for the transformers?

2T = load/source
2T = 320/80
T = 4/2
T=2
