Why transformer current has two components, at no load ... no load, current is drawn to supply the core losses and to magnetize the core. Hence there is one component to supply the losses which are eddy current and hysteresis, we call that current Ic,the second component is Im which is the current requires to magnetize the core material for the operation of the transformer. 3.4K views View 6 UpvotersIs no load current the same as excitation current?10/2/2019What percent is the no load current of the full load current in the ...3/14/2018How to calculate current of transformer with no load1/5/2018What is no load current in transformer?
