ABSTRACT

Research on superluminal phenomenon is a frontier of physics. The problem of superluminal associated with the longitudinal electric field is studied in this paper. It discusses the longitudinal electric field inside the metal wires and electrical energy transmission in DC circuits. In the metal wire, the difference of electrical potential drives the electrons and then forms a current. The potential energy of electrons is converted into kinetic energy. This process completes the cycle of energy conservation. In the case of the DC circuit, Poynting vector is just a mathematical definition, and there is no real energy flow. DC power is transmitted entirely in the metal wire. Theoretically, the longitudinal electric field is non-local, that is, the speed of the longitudinal electric field can be infinite. It gives the preliminary results of an experiment to measure the transient speed of longitudinal electric field in this paper.

5. 结论

(1) 在直流电路的情况，在导线内，电源产生的纵向电场把作用力施加于金属导线内的自由电子，静电场的电势差驱动了电子，形成了电流。电子的势能转化为电子的动能，消耗了电功率；同时，电池的化学能产生了电动势，补充了电能，完成了能量的转化和守恒。所以，直流电能完全是在金属导线内部传输的。

(2) 由于直流电路内的电位差以及电流，在金属导线界面外产生了稳定的环型磁场以及静电场。所以，坡印廷矢量仅仅是数学上的定义，事实上没有形成真实的能流，也就是说，没有电磁能流从导线外部传输到导线内部。

(3) 直流电场在金属导线内部瞬间重新分布的速度是允许超光速的。本文初步测量了电场瞬态重新分布的速度。
