Answer Posted / manikumar agcet
Normally gas filled tubes ie CFL
(carbon florocent lamp) have
negative resistance
characteristics ,hence at the
time of starting they takes
very high current
consequently voltage may
drop.Hence to reduce this
high starting current we
connect Ballast.Ballasts have
positive resistance
characteristics.hence it
balance the tube resistance.
