The potential difference is another measurement of voltage.The potential difference or p.d. is a measure of the energy transferred per unit charge by the charge carriers to the component, which transfers it to other forms of energy.
The unit for potential difference is volts (V).1 volt is the potential difference across a component that transfers 1 joule of energy per coulomb of charge that passes through it to other forms of energy.If a component uses 1 joule of energy per coulomb of charge passing through it the potential difference across the component is 1V.
