Abstract
The phenomenon of unequal contact voltages at the positive and negative brushes of a sliding current-collection system has previously been explained as being ohmic in nature. Measurements are now presented which suggest that it is due instead to a change in surface potential difference at the metal-gas interface, which occurs even without sliding.
