WebApr 5, 2024 · 1. I think that you are mixing up two things one is an arc and the other is a Townsend discharge. An electric arc is often formed by two electrodes coming together, creating a lot of heat and then the electrodes being separated to form a small gap in which the arc is formed. The very high temperature created causes a plasma (ionised gas) to … 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.
