Sometimes is there the amount of charge (energy) really over-supplied, and in addition the difference in conductivity of the plasma channel and the ground is enormous. The lightning channel in the air has a resistance of less than 1ohm per meter, width not exceeding 1 cm, soil hundreds to thousands of ohms per meter, but relative to the cube with edge of 1 m.
Wakati mwingine kuna kiasi cha malipo (nishati) kweli juu-Hutolewa, na katika addition tofauti katika conductivity ya channel plasma na ardhi ni mkubwa sana. channel umeme katika hewa ina upinzani wa chini ya 1ohm chaguo kwa kila mita, upana si ilizidi cm 1, udongo Maelfu kwa mamia ya ohms kwa mita, lakini jamaa na mchemraba kwa makali ya 1 m
