VELENCY ELECTRONS AROUND IT, ENERGISED ELECTRON GOT
VELOCITY STRIKES THE NEUTRAL ATOMS, CHARGES ITS FREE
ELECTRONS & THE PROCESS GOES ON THEN STARTS INERACTION WITH
THE PARALLEL CONDUCTOR'S SAME PROCESS, MORE CORONA EFFECT
OCCURS WHEN APPLIED VOLTAGE INCREASED MORE THAN 30 KV / CM,
THE EFFECT WILL BE EVEN MORE, WHERE THE CONDUCTOR DURTY &
COVERED WITH DUST, ALSO OCCURS AT ROUGH SURFACE OF THE
