Explain working principle and losses in transformer

Question

Accepted Answer

Transformers work on the principle of electromagnetic induction, with losses including copper losses and core losses.

Transformers work on the principle of electromagnetic induction, where a changing magnetic field induces a voltage in a coil.
Copper losses occur due to resistance in the windings, leading to heat generation.
Core losses include hysteresis losses (energy lost due to magnetization and demagnetization of the core material) and eddy current losses (energy lost due to circulating currents in the core material).
Efficiency of a transformer is calculated as output power divided by input power, with losses reducing efficiency.
Transformers are designed to minimize losses and improve efficiency through proper selection of materials and design considerations.
