A step-down transformer could have a primary-secondary turns ratio of 4:1.

Question

Quizplus · Accepted Answer

A step-down transformer has a higher number of turns in the primary coil than in the secondary coil. Therefore, the turns ratio in a step-down transformer is less than 1, which means that the primary-secondary turns ratio is less than 1:1. If the primary-secondary turns ratio is 4:1, it indicates that it is a step-up transformer, not a step-down transformer.
