Answer Posted / pritish
at the initial stage the voltage induced by the choke is nearly about 2000v due to the inductive property of choke and this high voltage is required to discharge the gasses from the filament of the tubelight. after the discharge id initiated it requires normal supply voltage to maintain the path for the gasses inside the tube.
