Answer Posted / mahavir jagdev
the choke along with the starter is used to give the high voltage start to the tube light which has heating filaments at both ends to ionize the gas inside. once the tube starts glowing then only 90 volts is required to keep it going, so the starter stops the current flow into the heating filaments and the choke uses it's impedence to absorb the extra voltage from 220 volts to keep the tube light voltage to 90 volts.
