WebNov 1, 2024 · This derived term is known as the displacement current density formula. This comes in use when time-varying fields are required. For a constant displacement vector, i.e. a constant charge density the displacement current density vanishes. So, the integral form of Maxwell’s equation is, ∫E . da = Q / ε 0 ∫B . da = 0 ∫E . dl = -∫δB / δt . (da) Webthe probability density is constant everywhere; (that is, plane waves are stationary states) but the probability current is nonzero – the square of the absolute amplitude of the wave times the particle's speed; illustrating that the particle may be in motion even if its spatial probability density has no explicit time dependence.
