On the site with residual electrostatic charge after lightning discharges, there is "over-supply" of charge (even thousands of megajoules; failure of the instrument may cause dust particles carrying a few millionths of Joule).
Kwenye tovuti na malipo mabaki umemetuamo baada yanayovuja umeme, kuna "juu ya ugavi wa" ya malipo (hata Maelfu ya megajoules, kushindwa kwa chombo huweza chembe za vumbi kubeba millionths wachache Joule).
