    How power imported or exported using grids between two or more state??

    there is a single grid system throughout the country.. if one state has more power it supplies others through a grid., if the same state is deficient of power it gets power from others by SAME GRID., how is this possible?? wats the principle?? :confused:

    the principle is ohm's law.

    you might read the thread on alternators started by Bassalisk.

    Synchronous machines connected in parallel are mechanically coupled by the grid, just as a team of horses is coupled by their harness equipment (is tack correct word?) .
