For an ideal transformer, if the ratio of secondary turns to primary turns is Nₛ/Nₚ = 2, find the voltage ratio Vₛ : Vₚ.

G1 Physics · Accepted Answer

Step 1: An ideal transformer satisfies Vₛ/Vₚ=Nₛ/Nₚ. Step 2: Read secondary-to-primary turn ratio as Nₛ:Nₚ=2:1 from source. Step 3: Therefore Vₛ:Vₚ=2:1. Answer A. Final answer: (A) 2 : 1.
