I would describe this differently. Think of the
wall of the cage (for starters) as having some thickness.

As more electrons (or holes, if some are handy) are
pumped 'in' they immediately (ok light speed limit
applies) repel each other, so the charge ends up on

A pretty question. Has anyone measured increased
belt drag in a van de Graaf?
(I'm not saying it doesn't happen, just not sure...)
