. Show Energy losses in a transformer

Best Answer

Efficiency of a practical transformer is never 100%. The following are the losses in a transformer. Leakage of  magnetic flux occurs which leads to energy losses. Energy is lost in the form of heat due to joule heating of conducting copper wires. Owing to repeated magnetization and demagnetization of iron core, energy is lost. This loss is known as hysteresis loss. Energy is also lost due to the production of eddy currents in the iron core. This type of loss can be minimized by using laminated cores.
