Answer Posted / a.sakthi
answer b) 1000 rpm is correct. because 120f/p =N.here N is
the speed of the motor. hence f and p is the input frequency
and no of poles on the stator or rotor respectively
(depending upon which one is the rotating portion of the
motor) so and so, in general rotor is rotating so the answer
b) is correct. if the stator is rotating, answer b) is correct.
thank you....

I have a current transformer with 1 main reading meter with transformer outside the building and a control panel having 5 CT reading meters with black round coils inside the building. I want to know, A) when current pass through the Transformers, will the current be reduced or be the same and after that B) when current pass through the CT meters with black round coils, will the current be reduced or be the same. C) in the above process will the reading of the main meter be same or different, from the total reading of all the 5 CT meters.
