| contents | Maxwell defined a true or total current in a way not widely used today. He said "... true electric current ... is not the same thing as the current of conduction but that the time-variation of the electric displacement must be taken into account in estimating the total movement of electricity". We show that true or total current is a universal property of electrodynamics independent of properties of matter. We use mathematics without a dielectric constant. The resulting Maxwell Current Law is a generalization of the Kirchhoff Law of Current used in circuit analysis, that also includes displacement current. The generalization is not a long-time low frequency approximation in contrast to traditional presentation of Kirchhoff's Law. The Maxwell Current Law does not require currents to be in circuits. It has been applied to three dimensional systems like the signaling system of nerve and muscle fibers. The Maxwell Current Law clarifies the flow of electrons, protons, and ions in mitochondria that generate ATP, the molecule that stores chemical energy throughout life. The currents are globally coupled because mitochondria are short. Focusing on Maxwell current reinterprets the classical chemiosmotic hypothesis of ATP production. The conduction current of protons in mitochondria is driven by the protonmotive force including its component electrical potential, just as in the classical chemiosmotic hypothesis. The electrical potential is now the electrical potential as defined in physical sciences by Maxwell partial differential equations. The conduction current is now just a part of the true current analyzed by Maxwell. Details of accumulation of charges do not have to be considered in analysis of true current because true current does not accumulate. It is true total current that provides the energy that generates the ATP, not just the protonmotive force. |
