Heating Effect of Electric Current
The correct option for why the bulb glows when the electric current passes through it is the heating effect of electric current. This phenomenon can be explained as follows:
Resistance in the Bulb Filament
- When an electric current passes through the filament of the bulb, the filament offers resistance to the flow of electricity.
- The resistance in the filament causes it to heat up due to the flow of electrons.
High Temperature in the Filament
- The high temperature of the filament due to the resistance causes it to glow and emit light.
- This is similar to how a metal coil in a toaster heats up and glows red when electricity passes through it.
Incandescence
- The process of producing light from a heated filament is known as incandescence.
- Incandescent bulbs produce light through the heating effect of electric current.
Conclusion
- In conclusion, the bulb glows when the electric current passes through it due to the heating effect of the current on the filament, causing it to emit light through incandescence.
