the movement of magnetic field in field winding of induction
machine. it moves in the clock wise or anti clockwise
direction but when this rotating magnetic field is equal to
the speed of the rotor then rotor will be in the lock out
condition. when the rotating magnetic field is less than
rotor speed. this is case in the Induction machines.
Ns=120f/P

Answer / coolclikker

Rotating magnetic field refers to the movement of magnetic
flux or field in stator winding around the rotor. this field
is generated by the poles on the stator of induction
machine. rotating magnetic field plays an important role of
magnetic induction and emf which is generated on the rotor
of the induction machine.

Before i went to bed my master bathroom lights were working fine. At 2 am, when I went to use the lights, none of them were working. The outlets throughout the bathroom work, but the lights and fan above the toilet don't. I have two panels of switches. The one panel has four switches. One of the switches turns on the hall light, and that works. The other three are to other lights, and they don't. The other panel has three switches. One of those is to the fan, and the other is to a light above the toilet. The other is a to light that is also on that other panel. I tried the breakers, and the one that turns off the outlets, marked for the bathrooom, turns on and off the outlets. None seemed to be tripped. I checked the lightbulbs, and they are fine. Please help

We say that if voltage in a power system is increased,for a constant power the current will decrease (by P=VI). isn't this in disagreement with the ohms law(I propotional V;resistant const.).Since the resistance of transmission lines remains constant,shouldn't inc in voltage cause inc in current across the transmission line? I have read many articles across the net but still couldn't this figure this out. :( Guyz plz assist me with dis..:)..
