Answer Posted / bikash chandra pal
some of our friends not agreed to my earlier reply . let me
clarify "earthing" & "grounding" are the terminology used
one in UK & other in USA. But the finally it mean the same
thing. ie . when some point of electrical system is made
fixed to ground (may be for safty purpose like equipment
body earthing or for system protection purpose like
transformer star point earthing. Hope the thing is clear.
if you are still in doubt, you may refer diffrent TEXT
BOOKs to check the same or search GOOGLE.

Stator of 3-phase IM has 3 slots per pole per phase. If supply frequency is 50 Hz, calculate the speed of rotating stator flux A 1000 rpm B 500 rpm C 1500 rpm D 1440 rpm
ii) A shunt motor supplied at 230V, runs at 900 rpm when the current is 30A. The resistance of the armature is 0.4 ohms. Calculate the resistance required in series with the armature to reduce the speed to 600 rpm, assuming that the armature current is then 20A. [12]
