Current and potential difference
WebApr 6, 2024 · The relationship between electric current and the potential difference is given by Ohm’s law which states that in any conductor, the flowing electric current is directly proportional to the potential difference between the two ends of the conductor. i.e., V ∝ I. Therefore, V = IR where R is the resistance of the conductor material.

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.
