प्रश्न
How will you prove experimentally that graphite is a good conductor of electricity?
उत्तर
- Objective: To prove that graphite is a conductor of electricity.
- Materials: Pencil, conductive wire, battery/cell, small bulb.
- Action:
- Sharpen the pencil on both sides.
- Now, connect the two ends of the pencil with electrical wires. Connect one end of the wire to the cell/battery and the other end to the small bulb. Connect the other side of the bulb and the other side of the battery with another short wire.
- Start current in the circuit and observe.
- Diagram:
An electric current flows through the graphite. - Observation: An electric bulb in the circuit lights up.
- Inference/Conclusion: This experiment proves that graphite in pencil is a good conductor of electricity.
