A volt is a potential difference across a conductor when a current of one ampere (Amp) dissipates one watt of power. Voltage is then defined as the pressure that pushes electrons (current) between two points to enable them to power something. Battery voltage refers to the difference in charge due to the difference in the number of electrons …
