For the purpose ofanalysis - exact equivalentcircuit of a transformer isusually replaced by anapproximate equivalentcircuit. In doing so - errorsintroduced due to windingohmic loss and core loss areof differential nature. Due tothis - the analysis byapproximate equivalent circuitgives fairly satisfactoryresults. Under thecircumstances - which one ofthe following statements iscorrect in respect of lossesreferred to approximateequivalent circuit ascompared to exact equivalentcircuit?
