starter for breaking & closing circuit with the help of
small relay element and choke for to make a voltage from
230v to 1000v for energise electrons (which are in the
argon gas & mercury)and closing & opening starter helps
voltage build up. according to the above process electrons
collision occurrs .so due to that avalanche breakdown
occuers and due to that more number of electrons
created .so the current flow inside the tube is get
increasing & lighting process takesplaces .if current
rising takesplace continuesly the tube light has to be
blasting.so inorder to avoid the blast we should control
the rising current .that can also be done by choke .so
without choke the tubelight get
fused.
if u can't belive me ,u can check that
