Answer 1

Answer with Explanation:

What will happen if an electric current is flown in the circuit in the figure?

→ When current is passed through the circuit, the bulb will glow as the path of current is not obstructed.

Which material is present in the pencil?

→ Graphite is present in the pencil

Which property of that material is found in this experiment?

→ The property of Graphite being a "Good conductor of electricity" is found in this experiment.

NOTE:

• In this question, both the ends of the pencil are sharpened and so on both the sides graphite is touching the wire.
• Graphite is a good conductor of electricity and so current flows in the given circuit.

• But if only one side is sharpened and another side is left unsharpened, then the current would not flow and the bulb won't glow as wood is an insulator of electricity.
