The propagation of electric fields through a wire is fundamentally linked to the behavior of charged particles, specifically electrons. When current flows, an electric field is present inside the wire, generated by the arrangement of these charged particles. Contrary to common misconceptions, the excess charge on the wire does not create the electric field within it; rather, it is the interaction of charges throughout the wire that facilitates this phenomenon. The discussion highlights the importance of understanding Jefimenko's equations and the Lorentz force law in explaining the motion of charges and the resultant electric fields.
PREREQUISITESElectrical engineers, physicists, and students studying electromagnetism who seek to understand the dynamics of electric fields in conductive materials.
Ohm's law relates the E-field inside a conductor to the current density. It works for both AC and DC circuits, so I am not sure what "differentiating" needs to be done.WoronerD said:It appears that nobody is differentiating between Ohms Law and how AC/DC works
