AC Generator & Transformer

If a transformer of an amplifier has output impedance 8000 Ω8000\ \Omega and the speaker has input impedance of 8 Ω8\ \Omega, the primary and secondary turns of this transformer connected between the output of amplifier and to loudspeaker should have the ratio

Show answer and solution

Answer: (d)

  1. For impedance matching: ZpZs=(NpNs)2\dfrac{Z_p}{Z_s} = \left(\dfrac{N_p}{N_s}\right)^2.
  2. (NpNs)2=80008=1000\left(\dfrac{N_p}{N_s}\right)^2 = \dfrac{8000}{8} = 1000
  3. NpNs=1000≈31.6≈32\dfrac{N_p}{N_s} = \sqrt{1000} \approx 31.6 \approx 32
  4. So the answer is (d) 32 : 1.
