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

Options

  1. A1000: 1
  2. B100: 1
  3. C1: 32
  4. D32: 1

Correct answer

D. 32: 1

Step-by-step solution

aligned & Z ₁ Z ₂ = ( N ₁ ~N ₂ )^2 & 8000 8 = ( N ₁ ~N ₂ )^2 & ~N ₁ ~N ₂ = 10 10 1 32 1 aligned
