Stator of three phase induction motor creates Rotating
Magnetic field.But why not Transformer?

Answer Posted / g.dharnendran

Because in induction motor there is an air gap whieh makes
the stator flux to rotate in the space but in transformers
rotating flux is not possible since the core act as a low
reluctance path and flux takes that path.

True or false question. 1.The fuse provide phase and neutral 2.power loss in electrical circuit can take place in (resistance or inductance or capacitance). 3.two phase system each phase has separated by a phase difference of (90 or 180 or 270 or 45). 4.3 phase balanced star connected load neutral current shall be (line current or phase current or zero or unity)
