Answer:
FALSE
Explanation:
Electric bulb (incandesant lamp) a filament made of tungsten. Tungsten has high melting point and high resistivity. When electric current passes through the filament, it starts to produce heat due to high resistivity of electric current.
This produces heat and with the heat it also produces some light.
Hence an incandesant lamp works on the heating effect of electric current, not chemical effect.
