As we understand, electrons can't be unmoving therefore electrons always moving or flowing. If the voltage is zero, where do the electrons move? Do they move everywhere?

1What do air molecules do when the wind isn't blowing? – John Doty Mar 24 '23 at 12:13

The air molecules are still moving around everywhere, so I guess same goes to electrons? I should've asked this on the chat though. So, zero volt reading on those instruments simply mean they can't detect electron motions that are too subtle? – SnoopyKid Mar 24 '23 at 12:18

1With a sufficiently sensitive voltmeter, you can detect thermal fluctuations in voltage. https://en.wikipedia.org/wiki/Johnson%E2%80%93Nyquist_noise – John Doty Mar 24 '23 at 12:25

So using a sufficiently sensitive voltmeter, these readings will be less than zero volts and will be in the negative numbers region? – SnoopyKid Mar 24 '23 at 12:27

1Thermal fluctuations are sometimes positive, sometimes negative. – John Doty Mar 24 '23 at 12:29

Not sure, Bob. My question is if the voltage is zero, does that means there is absolutely no flows of electrons. I think John Doty answered that question nicely – SnoopyKid Mar 24 '23 at 13:15

Also that means the ground in circuits actually have electrons flowing – SnoopyKid Mar 24 '23 at 13:16

Movement is not the same as flow. – Jon Custer Mar 24 '23 at 14:23

Can you explain why? – SnoopyKid Mar 24 '23 at 14:26
