Set up the circuit as shown with two free ends A and B. Check your circuit by switching on the current and touching A and B together.
Bulb should glow. Attach the wires/ fibres/thread one at a time to the ends A and B. Observe whether bulb glows or not. Tabulate your observations.
Observation: You will notice that the bulb glows in all the metallic wires tested. It shows that almost all of the metals are the good conductor of electricity.
