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. WebAug 30, 2024 · Can Electric Field Be Negative. Yes, electric field can be negative. This is because electric field is a vector quantity and its direction is determined by the direction of the force that would be exerted on a positive test charge. If the force on a positive test charge would be in the negative direction, then the electric field would be negative.
