Answer Posted / Ganesh Datt Tripathi
The stator magnetic field rotates at synchronous speed in an AC motor because it is generated by the stator winding which carries alternating current. The frequency of this rotation is equal to the line frequency (50 or 60 Hz) and is determined by Faraday's Law of Electromagnetic Induction.

In a Impedance Based Distance Relay (Quad Characteristics) - Could there be two different Line Angle(RCA) for Ph-Ph & Ph-Gnd? If So Kindly Let me Know.. Where, What are the advantages of the same?
1- XC and the RC time constant are both measures of the reaction of C to a change in ____? 2-The power factor is a numerical ratio with a value between 0 and 1 equal to the ______________ of the phase angle. 3-When V and I are out of phase because of reactance, the product of V times I is called ______________ power 4-For _____________ inductors, the branch currents can be added algebraically. 5- The ______________ power in watts can be calculated as I^2R 6-Calculate XL with L = 30mH and f = 1kHz ( I have Xl=2piFL 2*3.141592653*1kHz*30mH =188 ohms Please check) 7-A parallel RL circuit has the values, R = 5kohms, XL = 5kohms. A voltage source of Vt = 10Vrms is connected in parallel to R and L. Determine the total current, It delivered by the voltage source Vt. 8-A series RC circuit has R = 1Mohm and C = 1microF. How long would it take for the capacitor to fully discharge if it is initially fully charged? 9-A circuit has real power = 300W and an apparent power of 500VA. Determine the power factor and phase angle. 10-The time constant for an LR series circuit is T = 0.1s and R = 10ohms. Calculate the inductance L.
