Question

Filaments of electric bulbs are made from high resistivity materials give reason

Answer 1

Answer: high resistivity materials produce higher amount of heat.

Explanation:

high resistivity materials produce higher amount of heat.

higher the resistance higher is the heat .

In a bulb the filament is heated which makes the bulb glow.

so only such materials will be  choosen as the filament which can withstand higher temperature.

filaments are mostly made up of  tungsten .

this is why they are made up of high resistivity materials.
