Heating Effect in the Coils The primary and secondary coils are made … WebMar 23, 2024 · Copper losses or Ohmic losses. The copper losses occur in the windings of the transformer due to their internal resistance. If R is the total resistance of the windings of the transformer and I is the current drawn, then the copper loss is I 2 R (W). As the copper loss depends upon the current which changes with the change in load, making the …
