Notes

V_{ab} = \int_{r_{a} (C)}^{r_{b}} (E + \frac{\partial A}{\partial t}) d r

where $E$ is electric field strength (electric field strength), $A$ is magnetic vector potential (magnetic vector potential), $t$ is time (ISO 80000-3: Space and time), and $r$ is the position vector (ISO 80000-3: Space and time) along a given curve $C$ , from point $a$ to point $b$ .

See IEC 60050-121,locality:item="121-11-26".

V_{ab} = \int_{r_{a} (C)}^{r_{b}} (E + \frac{\partial A}{\partial t}) d r

où $E$ est le champ électrique (electric field strength), $A$ est le potentiel vecteur magnétique (magnetic vector potential), $t$ est le temps (ISO 80000-3: Space and time) et $r$ est le rayon vecteur (ISO 80000-3: Space and time) le long d'une courbe donnée $C$ reliant le point $a$ au point $b$ .
