WebNeutron Current Density The neutron flux, φ, does not characterize the flow of neutrons. There may be no flow of neutrons, yet many interactions may occur (I = Σ.φ). The … WebThe photon flux is defined as the number of photons per second per unit area: T he photon flux is important in determining the number of electrons which are generated, and hence the current produced from a solar cell. …
WebΦ = EA If the normal to the area is at an angle θ to the direction of the field then the flux through the area A is given as Φ = EACos θ Zero Flux: No electric field lines will pass through a surface when it placed parallel to the electric … In quantum mechanics, the probability current (sometimes called probability flux) is a mathematical quantity describing the flow of probability. Specifically, if one thinks of probability as a heterogeneous fluid, then the probability current is the rate of flow of this fluid. It is a real vector that changes with space and time. Probability currents are analogous to mass currents in hydrodynamics and electric currents in electromagnetism. As in those fields, the probability curre…
