Question

what happens if we replace tungsten filament by copper

Answer 1

The bulb will not glow white hot and copper will melt hence giving no light because of low resistance and resistivity too.

hope this helps if so mark as brainliest.

Answer 2

The bulb will not work properly as heat and light cells will get weak. Tungsten has a very high melting and boiling point and it offers a great amount of heat energy which is then converted into light. On the other hand, copper is a very light metal and offers low melting and boiling point and produces a small amount of heat and light energy. Copper cannot provide great amount of resistivity and it's resistance will be low.
