The vacuum-case equation is. ∇ ⋅E = ρ ϵ, ∇ ⋅ E = ρ ϵ, where ρ ρ is the (free) charge density. In the case of a polarizable medium, there will be bound charges as well as free charges, so we can write ρ = ρf +ρb ρ = ρ f + ρ b (you can infer the subscripts easily).So, for instance, the electric current I, is the flux of the current density vector J. Now a current is anything that can be written as a rate of flow of some quantity (eg : mass, charge, spin, probability). In the context of the above example, the electric current is also the rate of flow of charge.
