Which of the following statements is true concerning step-down transformer operation?

Correct Answer: Option B — The voltage supplied to the primary side is greater than the voltage produced by the secondary side.

Step-down transformers reduce voltage from primary to secondary. According to IEEE 45 and 46 CFR Subchapter J, the input voltage supplied to the primary winding must be higher than the output voltage produced by the secondary winding to achieve the step-down ratio.
