To match a $600 \Omega$ audio load to a $4 \Omega$ speaker system, the primary of the impedance matching transformer must have ـــــــــــــ more turns than the secondary.
A)150
B)12.2
C)3.06
D)The primary should have less turns than the secondary.

Question

Quizplus · Accepted Answer

The turns ratio (Np/Ns) of the transformer can be calculated using the formula:

Np/Ns = √(Zp/Zs)

where Zp is the primary impedance (600 ohms) and Zs is the secondary impedance (4 ohms).

Np/Ns = √(600/4) = √150 ≈ 12.2

Therefore, the primary must have more turns than the secondary, and the best choice is B.
