Que: Is it true that in India electrical power is transmitted from 3 phase, Star (Y)- Neutral configured secondary of some power transformer AND any Phase to Star neutral forms the configuration for Single phase-Neutral (P-N) power we receive in our homes? If YES, then (I) Phase is positive with respect to the Neutral during positive half cycle of sine wave. (II) Neutral is positive with respect to the Phase during the negative half cycle of the sine wave. IF THIS NEUTRAL IS EARTHED, THEN HOW DOES THIS POWER FLOW THROUGH THE ELECTRICAL LOAD? It flows through the Earth connection as this has lower impedance than the load, isn'it?
