WebIn short, an electric potential is the electric potential energy per unit charge. This value can be calculated in either a static (time-invariant) or a dynamic (time-varying) electric field at a specific time with the unit joules per coulomb (J⋅C −1) or volt (V). The electric potential at infinity is assumed to be zero. WebF = -dU/dx. E = -dV/dx (divide both sides by q) E*dx = -dV. Integrate both sides. Assuming E is constant in x, E*Δx = -ΔV, aka. Ed = - ΔV. This is saying that as a positive charge moves in the direction of an electric field, the voltage decreases, equal to the electric field strength times the distance traveled.
