A transformer has 400 turns and 200 turns in the primary and secondary windings respectively. If the current in the primary and secondary windings are 3A and 5A respectively. calculate the efficiency of the transformer?

[Is*Ns/ Ip*Np]*100= [200*5/ 400*3]*100
= [1000/1200]*100
=0.8333*100
=83.33%


I hope this was explanatory and helpful

Efficiency=power in secondary 100
÷ × ÷
Power in primary 1
