Question 1 of 5

A transformer utilizes an inductor to increase or decrease the voltage in a circuit. AC flowing in a coil wrapped around an iron core magnetizes the core causing it to produce a magnetic field. This magnetic field generates a voltage in a nearby coil of wire and, depending on the number of turns in the wire of the primary (source) and secondary coils and their proximity, voltage is induced in the secondary coil.

The voltage output of a transformer primarily depends on which of the following?

the conductor used for the wire in the coils

the number of turns in the wire of the coils

the diameter of the coils

the diameter of the wire in the coils
