Module 11. Aeroplane aerodynamics, structures and systems
A 4:1 step-up transformer receives 120VAC in its primary and has 1600 Ohms resistance in its secondary. What is the current drawn from the source?
•  3 A.
•  1.2 A.
•  0.3 A.

davide_gibbo asking:
•  Why 1.2? I think it's 0.3(480/1600)

Pls, do one more step, find current of primary coil \source connected to primary\, P=UxI, 120xI1=0.3x480, I1=1.2A.
