The amount of core material needed for a particular transformer is determined by the ____ rating of the transformer.
A) voltage
B) amperage
C) power
D) resistance

Question

Quizplus · Accepted Answer

The amount of core material required for a transformer depends on its power rating, which is expressed in watts or volt-amperes (VA). The amperage rating of a transformer is important for selecting the appropriate wire gauge for the winding, but it does not directly affect the size of the core. Voltage and resistance ratings are also important for transformer design, but they do not determine the amount of core material needed.
