What is the transformer ratio of a step-down transformer?

Education Journalist | Study Abroad Lead

A step-down transformer is a type of transformer that has fewer turns in the secondary coil than in the primary coil. This means that the voltage across the secondary coil is lower than the voltage across the primary coil. Therefore, the transformer ratio of a step-down transformer is always less than 1.

The transformer ratio is defined as the ratio of the number of turns in the primary coil to the number of turns in the secondary coil.
In a step-down transformer, the number of turns in the secondary coil is less than the number of turns in the primary coil.
This results in a transformer ratio that is less than 1.

The transformer ratio is an important parameter in determining the voltage output of a transformer. The voltage output of a transformer is given by the formula V₂/V₁ = N₂/N₁, where V₁ is the voltage across the primary coil, V₂ is the voltage across the secondary coil, N₁ is the number of turns in the primary coil, and N₂ is the number of turns in the secondary coil. Since N₂ < N₁ in a step-down transformer, the transformer ratio is less than 1, which means that V₂ is less than V₁.

Step down transformer

Therefore, the transformer ratio of a step-down transformer is always less than 1, as there are more turns in the primary coil than in the secondary coil, resulting in a lower voltage output in the secondary coil.
