Any breaks in the conductor keeps electrons from from flowing through a circuit. true or false?

[another_someone]

In DC terms, yes; but in AC terms, you can still have capacitance and induction effects that will cross over breaks.

Thank you.

Sorry, but it's one of those questions where "true or false" doesn't quite do the job. The answer is "sometimes".

Actually, any joint between conductors can have an oxide layer which, if it weren't for Quantum Mechanics, could prevent a current from flowing.

Of course, since in both the quantumn tunneling effects mentioned the "insulating" gap conducts current, the insulator must be a conductor.
Who said quantum physics wan't weird?

One day, you could find yourself sitting outside in the street. . .

Happens quite often on Saturday mornings, I'm usually accompanied by a traffic cone and a bad head.
