Is there any filament is used in a tubelight?
I found this qstn in this application..and the answer was Molybdenum..i think it was wrong..thats why i post this qstn..
Tube light do not contain any filament. That is why, they do not generate heat, and are therefore called cold sources of light. Their working principle is quite different from ordinary bulbs.
No.tubelight work by ionizing mercury vapour in a glass tube
