Sounds a daft question but I got thinking about another question and this cropped-up.
Background - In a conductor electrons move seemingly in a random fashion and more so when the conductor is warmer. When a voltage is applied there is a general tendency for electrons at one end of the conductor to start pushing electrons out at the other end i.e. there is a current flow.
But, as we are informed at school, the atom comprises mainly of empty space and, electrons appear to be a tiny object in that empty space so (with faint recollection of Heisenberg's uncertainty principle) and (ignoring anything I have previously learnt about how a BJT works), my question is this....
Question - If the plates of a capacitor were close enough would DC current flow?
