Correct answer is A as
(Np/Ns) ^2=Zp/Zs.
(Np/Ns) ^2=Zp/Zs.

Answer is B because v1^2/r1=v2^2/r2 assuming 100% efficiency.
So (v2/v1 = (r2/r1) ^0. 5 = k = 0.4:1.
So (v2/v1 = (r2/r1) ^0. 5 = k = 0.4:1.

Answer is A because n1/n2 = square root(z1/z2).
So Turn ratio is, n1 : n 2 = 2.5 : 1.
Where n1 = No.of primary turns.
n2 = No.of secondary turns.
z1 = Primary impedance.
z2 = Secondary impedance.
So Turn ratio is, n1 : n 2 = 2.5 : 1.
Where n1 = No.of primary turns.
n2 = No.of secondary turns.
z1 = Primary impedance.
z2 = Secondary impedance.

N = sqrt(Z1/Z2).
Where,
N = turns ratio
Z1 = Primary impedance
Z2 = Secondary impedance
Answer is A.
Where,
N = turns ratio
Z1 = Primary impedance
Z2 = Secondary impedance
Answer is A.

As transformer also used in Impedance Matching,
As we have relation square root (Zp/Zs) = Np/Ns.
Given Zp = 1000 ohm and Zs = 160 ohm then.
Np/Ns = Square root (1000/160) 2.5 : 1.
As we have relation square root (Zp/Zs) = Np/Ns.
Given Zp = 1000 ohm and Zs = 160 ohm then.
Np/Ns = Square root (1000/160) 2.5 : 1.

I think that here is the question about the secondary side of the transformer i.e. the secondary resistance of the coil means source resistance and when any resistance is connected across the source resistance is called load resistance.
Please suggest me, if I'm wrong.
