Question
When an electric current flows through the bulb, it lights as a result of
- Heating effect of electric current
- Chemical effect of electric current
- Magnetic effect of electric current
- Lighting effect of electric current
Hint:
The heating effect of the current cause the bulb to lighten.
The correct answer is: Heating effect of electric current
- The battery converts chemical energy into electrical energy.
- The outcome of the current flow can be used as a load.
- The bulb lightens when the electrical energy is converted into heat energy.
