With current flowing in the primary circuit, what voltage is induced on the secondary winding of the pole-mounted transformer?

In a typical pole-mounted transformer used in residential and commercial electrical distribution, the secondary voltage is often a standard voltage that is used for delivering power to buildings. In North America, transformers that step down from the primary distribution voltage (often in the range of several thousand volts) to a usable level for consumer electronics typically provide a secondary voltage of 240 volts for residential services.

This is consistent with many common applications, such as for household appliances that require 240 volts, which is standard for larger loads like ovens, dryers, and HVAC systems. Therefore, when the primary winding of the transformer operates with an alternating current (AC) voltage, it induces a secondary voltage that mirrors this typical distribution standard, leading to the conclusion that the voltage induced on the secondary winding of the transformer in this scenario is indeed 240 volts.

Other options reflect voltages that are either higher than standard residential service or not typically used in the context of a pole-mounted transformer designed for residential distribution, making 240 volts the most applicable choice.
