Current, Power & Potential Difference Through a Resistor

WebElectric Potential Difference. The electric potential difference between points A and B, V B − V A, 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. 1 V = 1 J/C. WebV = I x R where I is the current, in amps, and R is the resistance in ohms. To determine the potential difference, you need to know the current flowing through the resistor, and the value of the resistor. Multiply the two, and you have voltage or potential.
