Electrical machine Question.(Transformer)?

Find full load current of transformer. What do it mean by full load current? 100% efficiency, or maximum load in secondary winding?Let R1 32ohm, R20.05ohm, X1 45ohm, X2 0.06ohm.1 is in primary and 2 in secondary winding.R0250kohm, Xm 30kohm(R0 and Xm are the values refered to primary)How to calculate the full load current?

Answer:

there are many criterion it is application dependant or power it is the load that causes a temperature rise that if loaded beyond it will cause failure of course it depends on the insulation material so a smaller transformer could have a much higher rating because it can stand more heat small electronic stuff will generally be when the transformer can no longer sustain the output voltage Anita
