alleryIn a transformer with N₁ = 100 (primary), N₂ = 500 (secondary), if input is 10 V, output is:
A50 V (step-up: V₂ = V₁ × N₂/N₁)
B100 V
C2 V
D5 V
Answer & Solution
Correct answer: A. 50 V (step-up: V₂ = V₁ × N₂/N₁)
V₂/V₁ = N₂/N₁.
So V₂ = 10 × 500/100 = 50 V. Step-up transformer (N₂ > N₁).
For ideal transformer, power conserved: I₂ = I₁ × N₁/N₂.
