Experimental Data and Theories on Return Stroke Speed,the speed of light, and to date there is no consensus among researchers as to the cause of this speed reduction in the return stroke front. However, return stroke speed is an important parameter in return stroke models, and almost all the return stroke models available at present use return stroke speed as an input parameter.

Weltweite Sorge, nicht weltweites Netz,g strike. Note also that for a given strike point the magnetic field at the point of observation has opposite polarities for negative and positive return strokes. This is so because the directions of positive current are opposite to each other in the two cases.

It is important to recognize that to create an electrical breakdown, it is not sufficient for the electric field to reach the critical value at a point. The electric field shoul

Consider an electromagnetic field generated by a radio antenna tuned to a given frequency. If the ground is perfectly conducting, at any given point on the ground the electric field is perpendicul
