A current transformer with bar primary has 500 turns in its secondary winding. The resistance and reactance of the secondary circuit are 1.5Ω and 1.0 Ω respectively, including the transformer winding. With 5A flowing in the secondary winding, the magnetizing MMF is 100AT and the core loss is 1.2 W.
