WebSep 12, 2024 · Electric Potential Difference. 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. WebJan 19, 2024 · 3. So technically, in those physics examples the voltage isn't fixed in those batteries. The potential drops, just very slowly for small currents. For example, if the voltage is 12V and some small current flows, the voltage drops. However, it drops to like, say, 11.9999935434V or whatever. So for the problem you don't really care and you just ...
