Can you list some devices that rely on potential difference for their operation?

Potential difference (or voltage) is a measure of energy, per unit of charge, transferred between two points in a circuit. Apr 4, 2023 ... Potential difference is the work done by a charge carrier (electron, ion, etc) when passing through an electrical component. By conservation of energy, the kinetic energy has to equal the change in potential energy, so K E = q V . The energy of the electron in electron-volts is ...
