Power current potential difference

Web12 Sep 2024 · The electric potential difference between points A and B, VB − VA is defined to be the change in potential energy of a charge q moved from A to B, divided by the charge. Units of potential difference are joules per coulomb, given the name volt (V) after Alessandro Volta. 1V = 1J / C WebThe equation V = IR means that the potential difference, or voltage, across a resistor can be found by multiplying its resistance by the current flowing through it. The unit of potential difference is the Volt (V), which is equal to a Joule per Coulomb (J/C).
