Question

An ideal transformer will have maximum efficiency at a load such that
A)copper loss = iron loss
B)copper loss < iron loss
C)copper loss > iron loss
D)none of the above

Quizplus · Accepted Answer

An ideal transformer achieves maximum efficiency when the copper loss (loss due to the resistance of the windings) is equal to the iron loss (loss due to the magnetic properties of the core).
