Question

In a three phase alternator, there are __________ independent phase windings or coils.

(a) 1

(b) 2

(c) 3

(d) 4

The question was posed to me in homework.

My question is taken from Inter Connection of Three-Phase Sources and Loads topic in portion Polyphase Circuits of Network Theory

Answer 1

Right option is (c) 3

For explanation I would say: In a three phase alternator, there are 3 independent phase windings or coils. So, 3 independent phase windings or coils. The end connections of the three sets of the coils may be brought out of the machine to form three separate single phase sources to feed three individual circuits.
