The displacement of charge in response to the force exerted by an electric field constitutes a reduction in the potential energy of the system (Section 5.8). If the charge is part of a steady current, there must be an associated loss of energy that occurs at a steady rate.

WebDrift velocity is proportional to current.In a resistive material, it is also proportional to the magnitude of an external electric field. Thus Ohm's law can be explained in terms of drift velocity. The law's most elementary expression is: =, where u is drift velocity, μ is the material's electron mobility, and E is the electric field.In the MKS system, drift velocity … http://hyperphysics.phy-astr.gsu.edu/hbase/electric/diverg.html
Webelectric charge density. It is the amount of electric charge per unit volume. What this tells you is that divergence of E is caused by the presence of electric charge. In particular, if you have an empty region of space or a region where nothing has electrical charge then E has divergence equal to zero. Now, that looks like a very abstract
