alleryIn a transformer, the ratio of secondary to primary voltage equals
AThe ratio of secondary to primary turns (N₂/N₁)
BThe ratio of primary to secondary current squared
CUnity always
DThe ratio of primary to secondary turns (N₁/N₂)
Answer & Solution
Correct answer: A. The ratio of secondary to primary turns (N₂/N₁)
For an ideal transformer V₂/V₁ = N₂/N₁ (turns ratio).
Conservation of power gives I₂/I₁ = N₁/N₂.
