Traditionally, under "Theory N", when a battery is connected via two wires to a resistor or lamp, the battery delivers electric current/charge into the wires. Once the wires gain current/charge, they create magnetic and electric fields between the two wires. Now more than a century ago, when confronting a challenge similar to that of interconnecting high speed logic, Heaviside said; "We reverse this .... ". [Theory H]. The battery delivers electromagnetic field between the connecting wires. In its turn, the field causes electric current/charge in/on the wires. He called the field, travelling at the speed of light, "energy current". However, Heaviside's work on electromagnetic theory disappeared from the record. He was unreferenced in any text book for more than half a century.

There the matter rested for a century, until Catt realised that the core problem was for the battery to deliver energy/power to the resistor or lamp. If the battery delivered the electromagnetic field, it was generally agreed that the field carried the energy/power directly into the resistor or lamp. (After all, sunlight is "Energy Current".) Under the new "Theory C", electric current/charge played no role in the key activity, that of delivering energy/power from battery to resistor or lamp.

So, under "Theory C", what are electric current and electric charge? What is the role of the interconnecting wires? The answer is that when travelling along in the dielectric between the wires, some of the energy current (or electromagnetic field) penetrates into the wires. Since the dielectric constant of copper or any other conductor can be shown to approach infinity , the velocity of penetration, which depends on the inverse of the dielectric constant, approaches zero. Also, the impedance of a conductor approaches zero, so that very little of the energy current enters the conductors (in the same way as, if we have large and small resistors connected in series, very little power is dissipated in the small resistors.) Maxwell's Equations link field and electric current/charge, and the so-called (but non-existent) current and charge are merely mathematical manipulations of the electromagnetic field.

Theory N.

Let us look at how two rails guide a train.

The rails prescribe a region of space, the space within the rails. The rails say that no part of the train is allowed within that space.

If the rails are not perfectly rigid, a little of the train enters the region belonging to the rails. Similarly, but not exactly, if the conductors are not perfect, a little energy enters the region belonging to the conductors.

You will realise that no professor or text book writer would be willing to think through the above.
