Questions about electricity.

2. "Static charge" is generated by concentrating charged particles in one place, with nowhere for them to go. It's measured in coulombs, not volts - voltage only applies to complete circuits.

I would think voltage would still be a valid metric, not of how much charge you have stored exactly, but of how badly that charge wants to leave. There is still an electric potential difference, and you can still lose or gain electrons from the atmosphere (but then what happens in a vacuum.. huuh).

Valid yes. All charges have an electric field, and that somehow is linked to lines of equipotential. I'm not sure, I think I was asleep at the time.
