Which statement describes the relationship between the primary voltage and secondary voltage in an ideal transformer?

In an ideal transformer, the voltages are determined by the turns ratio. The primary and secondary voltages satisfy Vp/Vs = Np/Ns, so the primary voltage is proportional to the turns on the primary and the secondary voltage scales with the turns on the secondary. Equivalently, Vs = Vp × (Ns/Np). This means the output voltage changes in proportion to how many more or fewer turns exist on the secondary relative to the primary. The other statements don’t hold in general: voltages aren’t equal unless the turns are the same, and the secondary voltage isn’t inherently twice the primary unless the turns ratio is 2:1.
