Answer Posted / rakesh
as we know that R=p*l/a
resistance of the
conductor is inversely proportional to the cross sectional
area of the conductor .Hence bigger cross sectonal area
reduces the resistance and provides a easy path for the
current flow.So the Earth Pin is always bigger than the
other two pins in a 3pin plug.

In case of salient pole alternator when number of poles are 4 or more than 4 it helps the flux wave to be sinusoid as air gap length is increased from center to tip , but if the number of poles are 2 how does the flux wave is sinusoidal?
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.
