Question
The setup shown below works as a simple switch as the ____.
- Paper clip is metallic
- Drawing pins are metallic
- The cardboard is not metallic
- All of the above
Hint:
The bulb will glow as the current is carried by the conductors.
The correct answer is: All of the above
In the above figure, the setup will work because,
- The switch which is made up of paper clip and drawing pins are metallic in nature, so they are a good conductor of electricity.
- The base is made up of cardboard which is an insulator, it insures the flow of current remain in the circuit and does not spill into the surroundings thus, protecting the user from the electric shock.
