transformer the core loss is 100 watt at 40 Hz and 72 watt at 37 Hz, then eddy current and hysteresis

Assume a single phase transformer with primary and secondary winding. Explain what would happen if a third winding with a constant DC voltage would be added to the same magnetic circuit. ...

Define all the losses in the transformer with the diagram and then define the hysterisis loss with thw graph.

In a transformer that has 10 times more turns on the secondary side (side 2) than on the primary side (side 1), the magnitude of the voltage/EMF across the windings on the secondary side, E₂ will be... O a.... 10 times lower than the voltage/emf on the primary side, E₁. O b.... the same as the voltage/emf on the primary side. O c.... always zero regardless of the voltage on the primary side, E₁. O d.... 10 times higher than the voltage/emf on the primary side, E₁.
