Web18 sep. 2012 · Maxwell's equations consist of 8 equations and 10 unknowns, not just 6 unknowns for the fields. Ten unknowns comes from including the charge and current density amoung the number of unknowns. There is one unknown for charge density and 3 unknowns for current density. The charge and current density are not unknowns. Web4 feb. 2024 · Start by taking the time derivative of the Coulomb's law Maxwell's equation to get ∇ ⋅ ∂ t E = 1 ϵ 0 ∂ t ρ. By the continuity equation the right hand side becomes ∇ ⋅ ∂ t E = − 1 ϵ 0 ∇ ⋅ J. Now this is interesting, because it implies that the divergenceful parts of ∂ t E and J are proportional, i.e. (2) ∂ E d i v ∂ t = − 1 ϵ 0 J d i v.
