ays the same. Transformers 157 The losses in the transformer are due: First, to theohmic resistance of the coils; second, to inefficiency ofthe magnetic circuit provided by the iron core; third,to eddy or foucault currents generated in the ironcore and also in the copper wires themselves (this… … Figure 101 The losses due to ohmic resistance can be reduced byusing larger wire of higher conductivity. The lossesdue to foucault currents are kept at a minimum bylaminating the iron core of the transformer. Sincefoucault currents are induced by lines of force whichact at right angles to the…
