Explanation:

Electric bulbs do not glow due to the chemical effect of electricity. The correct answer is option 'B', which states that the statement is false. Electric bulbs actually glow due to the phenomenon of thermal radiation and the flow of electric current through a filament.

Thermal Radiation:
Electric bulbs, especially incandescent bulbs, work by passing an electric current through a filament made of tungsten. The filament has a high resistance, causing it to heat up when electricity flows through it. As the filament heats up, it emits light in the form of thermal radiation. This radiation occurs when the heated filament emits electromagnetic waves, including visible light.

Flow of Electric Current:
The flow of electric current through the filament is necessary for the bulb to glow. When an electric current passes through the filament, the resistance of the filament causes it to heat up. The filament reaches such a high temperature that it emits visible light, causing the bulb to glow.

Chemical Effect of Electricity:
The chemical effect of electricity refers to the reactions that occur when electricity passes through certain substances, such as in electrolysis. It involves the movement of ions or electrons, leading to chemical changes. However, in the case of electric bulbs, the glow is not a result of any chemical reaction. Instead, it is primarily due to the thermal radiation and flow of electric current.

Conclusion:
In conclusion, electric bulbs do not glow due to the chemical effect of electricity. The glow is a result of thermal radiation emitted by the heated filament and the flow of electric current. Understanding this distinction helps to clarify the true cause of the glow in electric bulbs.
