​

Answer 1

Answer:

I think it's heating effect

Answer 2

a) Heating effect is the correct answer.

• The electric current reaches the filament of electric bulb.
• The filament then gets hot and produces light energy.
• Thus, electric bulb works on the heating effect of electric current.
• Therefore, electric bulb is also commonly used for providing hot environment along with light.
• The filament used in electric bulb is made of tungsten which has higher melting point, and thus doesn't melts on heating.
