I was thinking about when current can and can't flow to ground. I came up with that current will only flow to ground when we have at least two grounds in the circuit, since then we have a complete circuit and current can flow. I can't however, think of why current will not flow to ground if we only have one ground in the circuit? I would say that it is because the we do not have a closed circuit through which current can flow. But, current, does not need a closed circuit to flow (like with a capacitor). So please can you explain why current does not flow to ground if we only have one ground (or if current does flow to ground if we have only one ground why)?
When I say ground I mean actually physically attached to the earth rather then a conductor (I say this because the earth has so many more electrons that a electrons flowing to/from it would have a negligible effect on the overall number of electrons in it) does this make a difference??
The following circuit is one where I think current should flow to and from ground (sorry for the poor diagram my computer is slow so I can't draw a proper one)
