I would like to know if electricity will follow a path of least resistance on a rotating conductor.
Please reference the drawing below.
This is showing a rotating non-conductive disc with a strip of copper around its perimeter and there are two brushes (blue squares) which the DC electrical current is flowing through. Say that this disc is 4 inches in diameter and the copper strip is moving at a rate of 130 fps.
Would electricity take the path indicated in the drawing since the free electrons would be moving with the atoms in the copper strip in contrast to the other available path, in which the free electrons would have to flow against the oncoming atoms in the copper strip?
Also, as a secondary question concerning this setup, would centrifugal force acting on the copper atoms and on the free electrons have any effect on the flow of electricity?
