No load test has been conducted on an induction motor for different supply voltages and input power vs voltage plot has been drawn. The curve is extrapolated to intersect the y-axis. This point is?

(a) friction and windage losses

(b) core losses

(c) stray losses

(d) all of the mentioned

I have been asked this question in a national level competition.

The doubt is from Applications of Polyphase Induction Motors in section Induction Machines of Electrical Machines

Best answer
Right option is (a) friction and windage losses

To explain I would say: The extrapolated point is friction and windage losses of the induction machine.
