The electric field divergence will be zero only if the net change is zero. In the current density formula, we count all charges that will move with a non-zero average velocity, when an electric field is applied, and thus will contribute to the electric current. Share.
The distribution of electronic charge is described by the electron density that determines the amount of negative charge per unit volume.” [ 2, p. 255] The idea here is that the amplitude-squared of the quantum wave function gives the density of electron charge (exactly how will be explained in Sect. 2 ).Conduction by holes is studied later in Condensed Matter Physics.
