Transformer — Turns RatioHardQuestion 20188

Question

An ideal step-up transformer has n₁ = 100 turns and n₂ = 500 turns. If primary voltage is 220 V, the secondary voltage is:
  1. A
    44 V
  2. B
    1100 V
    Correct
  3. C
    220 V
  4. D
    440 V

Correct answer

1100 V

Explanation

V₂/V₁ = n₂/n₁ = 500/100 = 5. V₂ = 5 × 220 = 1100 V.
