In an ideal transformer, the turns ratio is $\dfrac{N_p}{N_s} = \dfrac{1}{2}$. The ratio $V_s : V_p$ is equal to (the symbols carry their usual meaning) :
Answer: (D) $2:1$
Concept. Ideal transformer: $\dfrac{V_s}{V_p} = \dfrac{N_s}{N_p}$.
Step 1. Ratio. $\dfrac{N_s}{N_p} = 2$, so $V_s : V_p = 2 : 1$ (step-up).
Answer. $2 : 1$ (Option D).
