Kind of a basic doubt here, but it has been nagging me for a while now. The electric field generated by a power station is a non-conservative one, and it varies as 1/r with respect to the distance of a point from the source.( I am assuming this statement is accurate.) So what I don't get is how electricity is transmitted over such great distances. I mean, they way I see it, a greater distance means a smaller electric field, which would set up a smaller current. So, over thousands of kilometers, the electric field should be of a magnitude too small to set up a significant current. I am definitely missing something crucial here, so any sort of clarification would be greatly appreciated.
