Charge flow equation physics
WebA continuity equation is useful when a flux can be defined. To define flux, first there must be a quantity q which can flow or move, such as mass, energy, electric charge, momentum, number of molecules, etc.Let ρ be the volume density of this quantity, that is, the amount of q per unit volume.. The way that this quantity q is flowing is described by its flux. WebIn equation form, electric current I is defined as I = Δ Q Δ t where Δ Q is the amount of charge that flows past a given area and Δ t is the time it takes for the charge to move past the area. The SI unit for electric current is the ampere (A), which is named in honor of the French physicist André-Marie Ampère (1775–1836).
