In a given transformer for given applied voltage, losses which remainconstant irrespective of load changes are
A)friction and windage losses
B)copper losses
C)hysteresis and eddy current losses
D)none of the above

Question

Quizplus · Accepted Answer

Hysteresis and eddy current losses in a transformer are independent of the load and remain constant for a given applied voltage. These losses are associated with the core and occur due to the magnetization and demagnetization of the core material and the circulation of induced currents within the core, respectively.
