Describe a simple expirement to differentiate good conductors from bad conductors?
Make a simple circuit with a bulb, connecting wires and a cell with an empty space to check the conductivity of material. To do this experiment you will need:
1. Connecting wires
3. Two cell battery
4. Iron nails
5. Materials to check good or bad conductor of electricity
Make the circuit as shown in the following figure:
Place the material between the A and B end and if the material is conducting the bulb will glow otherwise it do not.
