Why it is the energy produce from the movement of electrons?
Energy also requires a voltage. The unit of energy is called the "electron-volt".Why it is the energy produce from the movement of electrons?

You can look up "electron volt" in Wikipedia.
That is a peculiar statement to make. It is not wrong, but different. Voltage is the energy density of the charge.Ratch
Please quantify your energy. If you need to express an amount of energy, you must use a scientific unit of energy. I chose electron-volt because the OP is talking about electron charge. What units are you using?
Hi alisa01,Why it is the energy produce from the movement of electrons?
guess you could call the change in voltage a change of charge density.
higher to lower via gravity? more to less, or electron flow or conventional flow? I know, don't go there.
No, a change in the energy density per unit charge.
Like V = W / Q
Voltage equals total Energy per unit charge.
You misunderstand. "W" does not stand for "watts". "W" is the scientific symbol for energy, joules. Power, in watts symbol is "P". I guess the standard came from the use of "W" for Work, which physics terms, is the same as energy.Not watt/coulomb, but joules/coulomb.
That's V(Voltage in volts) =(equals) W(energy in joules) /(per) Q(unit of charge in Coulombs)
Yes indeed, W is the energy required to concentrate that charge. Not "energy density per unit charge". Just plain old energy per unit charge. If you disagree with V = W / Q, then
show us your math. Back up your opinion with some figures.
Yes, your equation is correct if you mean "W" for energy. You will excuse me, as my dictionary lists "W" as the international symbol for watts, as does this link. https://en.wikipedia.org/wiki/Watt
Volts = joules/coulomb is a density because it relates an amount of energy to charge in MKS units.
