A 30 ohms resistive load is to impedance matched to transformer to a source having an internal resistance of 3000 ohms. The ratio of primary to secondary turns of transformer should be:

  1. 0.1
  2. 1
  3. 10
  4. 1000

Correct answer: 3. 10

SolutionL

(N1/N2)2 = Zp/Zs

(N1/N2)2 = (3000/30)

(N1/N2)2 = 100

N1/N2 = 10
