Activity 3.6 Class 10 Science Explanation

This activity is adapted from Chapter 3, "Metals and Non-metals." In this activity, we will learn about the electrical conductivity of metals.

Aim

To test whether metals can conduct electricity

Materials Required

    1. Cell or battery

    2. Bulb

    3. Connecting wire

    4. Metal samples

    5. Switch

   Procedure

  We first set up an electric circuit in which we use a battery, a bulb, a switch, and connecting wires. We leave a small gap between the two terminals A and B in which a metal sample will be inserted.

      

   We turn on the switch and observe whether the bulb glow or not.

   Observation

   The bulb glows.

   Explanation

  When the metal sample piece is inserted between the terminals A and B, it completes the circuit and allows the current to flow, which is why the bulb glows.

   Metals have free electrons, which allow electric current to pass through them.

   Conclusion

  This activity demonstrates that metals are good conductors of electricity.

    Frequently Asked Questions

    1. Which metals are used for electrical wiring?

Answer- Copper and aluminium

    2. Do non-metals conduct electricity?

Answer – Most of the non-metals do not conduct electricity, but graphite (an allotrope of carbon) is a good conductor of electricity.

    3. What does it mean if the bulb glows?

Answer – It means electricity is passing through the circuit.
