Homework Statement
Why is a tungsten filament used in incandescent bulbs?
I earlier thought that it was due to the high resistivity of tungsten , but i was wrong , the resistivity of tungsten is low at 5.2 * 10^-8 Is it due to its high melting point?? I can't figure out as high melting point doesn't seem to be the only reason for selection of Tungsten.
Please Help.
Thank You
