Why an electric bulb is not filled with air but is filled with argon or nitrogen?

Answers

Answered by chandresh126

You can't fill a bulb with air or hot tungsten wire will combust in presence of oxygen. You can't maintain vacuum either or external atmospheric pressure will break the glass. So, u hav to fill it with non-reactive gas like nitrogen.
