Question

differentiate the material into conducters and insulators in your home and write a brief note

Answer 1

Conductors :
1.Conductors are the materials that allow the electric current or heat to pass through them.
2.Rate of conductivity is high.
3.Free Electrons are more and movement is free.
4. Electric field exist on the surface but remain zero inside the conductor.
5. They are used in making electrical wires and conductors.
Examples :Iron pans
Aluminum vessel
Silver articles.
Copper bottom pans.
Aluminum pressure cooker.
Stainless steel utensils.


Insulators :
1.Insulators restrict the electric current or heat to pass through them.
2. electric field do not exist on insulators
3. Thermal conductivity rate is very low.
4. Absence of free electrons.
5.They can be used as an insulation in electrical cables or conductors , for supporting electrical equipment.

Examples :
Rubber
Wood
Paper
Plastic.
Bakelite handles used for pans and cookers.
Bakelite switch boards.
melamine Fire proof apron which can be used while cooking.
Melamine plates and mugs. 
Teflon coating on Frying pans .
