Last Answer : An ideal transformer will have maximum efficiency at a load such that copper loss equal to iron loss.
Description : For a transformer, operating at constant load current, maximum efficiency will occur at?
Last Answer : For a transformer, operating at constant load current, maximum efficiency will occur at unity power factor.
Last Answer : D.C. generators are normally designed for maximum efficiency around full-load.
Last Answer : The condition for maximum efficiency for a D.C. generator is variable losses equal to constant losses.
Last Answer : Generators for peak load plants are usually designed for maximum efficiency at 50 to 75 percent full load.
