when we start the tube light, then it takes initially 1100
volt, after glow it takes 120 volt?(when we give 220 volt a.c.)

Answer Posted / amarnath

In a Tubelight we have a Choke which is made of Copper or
aluminium coil and when power is supplied this choke acts
as an inductive load and for inductive load initial voltage
required to start is more hence it is so.
