Its width depends almost only on the Return Stroke current (peak) and is of course very different for example between the discharge of 3 thousand amperes and 600 thousand. On the fact that after the lightning discharge appearing vertically into the ground may be affected corn plants quite accurately in a circle, therefore the corona discharge may contribute very significantly.
Upana wake unategemea karibu tu juu ya Return Stroke sasa (kilele) na ni mwendo wa tofauti sana kwa mfano Kati ya utekelezaji wa 3000 na amperes 600,000. On FACT Kwamba baada ya kutokwa umeme Akionekana vertikalt ndani ya ardhi inaweza kuwa walioathirika nafaka mimea kabisa usahihi katika mduara, hiyo kutokwa corona inaweza sana Kuchangia kwa kiasi kikubwa.
