argon and neon are gases which are non-conductors of electricity then how does current flow in a lighted bulb?

Expert Answer:

Dear student

When electric current is passed through the filament of the bulb; it becomes red hot and emit lights. To protect this filament from evaporating or catching fire, the bulbs are either evacuated or filled with inert gases like neon or argon.


Hope this helps.
