Question

In a given transformer for a given applied voltage, losses which remain constant irrespective of load changes are

• A. friction and windage losses
• B. copper losses
• C. hysteresis and eddy current losses
• D. none of the above

Answer 1

The correct option is C hysteresis and eddy current losses

In a given transformer for a given applied voltage, losses which remain constant irrespective of load changes are hysteresis and eddy current losses The losses that can occur in a material are: Iron losses: Iron loss is caused by the alternating flux in the core and consists of hysteresis and eddy current losses. of coercivity on the curve. (The reversed magnetizing force has flipped enough of the domains so that the net flux within the material is zero.)
