level questions: Transforer inefficentd

QuestionAnswer
What places can inefficiencies in transformers transpire fromcore wires
Where do the inefficiencies occur from from the coreInduced eddy currents The reversal of magnetism Poor insulation between the primary and secondary coil
Whta are ways to reduce energy loses in tranformers?Just need frst two probs Making the core from soft iron or iron alloys to allow easy magnetisation and demagnetisation and reduce hysteresis loss Laminating the core Using thick wires, especially in the secondary coil of step-down transformers Using a core that allows all the flux due to the primary coil to be linked to the secondary coil
Why does the reversal of magnetism cause innefecienesBecause reversal of magnetism requires work to be done
Why are eddy currents badEddy currents heat up the core cauing the energy to be wasted as heat energy
What does laminating the core actually do?Laminating the core means it has a higehr resitance making eddy currents less likely to occur and waste less enrgy
Whats the purpose of the coredirects the magnetic field round to the secondary
