Prepare an electric circuit as shown in the figure. This circuit is used to test whether electricity can pass through a material or not. Repeat this activity with different materials shown in the table.Observe and group these materials into good conductors and poor conductors:Electrical Conductivity of Materials\t\t\tS. No.MaterialsGood Conductor/Poor Conductor1.Iron rod/nailGood conductor2.SulphurPoor conductor3.Coal piecePoor conductor4.Copper wireGood conductor\tWe see that iron nail and copper wire are made of metals and are good conductors. So, we can say that metals are good conductors.
