Hi, I have a question on a quote I saw from Steinmetz regarding the two components of eletric field (magnetic and dielectric) To quote, ''Unfortunately, to a large extent in dealing with dielectric fields the prehistoric conception of the electro- static charge (electron) on the conductor still exists, and by its use destroys the analogy between the two components of the electric field, the magnetic and the dielectric, and makes the consideration of dielectric fields unnecessarily complicated.'' Steinmetz continues, ''There is obviously no more sense in thinking of the capacity current as current which charges the conductor with a quantity of electricity, than there is of speaking of the inductance voltage as charging the conductor with a quantity of magnetism. But the latter conception, together with the notion of a quantity of magnetism, etc., has vanished since Faraday's representation of the magnetic field by lines of force." Steinmetz is considered a legend in electrical engineering, yet he references a "prehistoric" notion of charge on conductor. Why do we still use charges on conductors? What made us abandon the dielectric field? Why have we strayed from lines of force? Thanks.
