Question

Suggest an experiment to compare the conductivity of electricity by iron, copper, aluminium and zinc. Perform the experiment​

Answer 1

AIM :-

To compare the electrical conductivity of different metals.

APPARATUS :-

cell, torch bulb fitted in a holder,connecting wires, different metal strips.

PROCEDURE :-

1. Let us make a simple circuit by connecting one end of the torch to cell and other end end of torch to metal strip and to cell back .

2. Let us insert a piece of Aluminium foil between the wires .And we will observe.

3. Repeat the same activity with different metal strips like Iron, copper and Zinc .

OBSERVATION :-

1. In case of aluminium,iron,copper and zinc we observe that , bulb glows in the circuit.

2. This experiment proves that all metals are good conductors of electricity.

3. Copper wire is the best conductor among all the metals.

CONCLUSION :-

This experiment proves that all metals are good conductors of electricity and

Copper wire is the best conductor among all the metals.
