Difference between conductor and insulator

Difference between conductor and insulator:

What is conductor:

Generally conductor is a material which is allow the current from one place to another place. otherwise we can say the material which is allowing  current flow then that material is called conductor. the some example of conductor is coper, aluminum, silver, gold, etc.

What is insulator:

insulator is a material which is not allowing current flow from one place to another. some examples of insulator are rubber, porcelain, glass etc.

difference between conductor and insulator

Now we can see about difference between conductor and insulator below,




   1 Electrical conductivity is good and large number of electrons move from one side to other side.

Example: coper, aluminium, silver, brass, iron

Electrical conductivity is not good. Electrons are not moving from one side to other.

Example: glass, plastic, wood, porcelain,rubber

  2. The resistivity is increase with increase in temperature Resistivity is remain constant either temperature decrease or increase
  3. Conductor having metallic bonding Insulator having ionic and covalent bonding
  4 Conductor having low electronegativity Insulator having high electro negativity
 5. Only one valance electron very loosely bound to the atom Valance electrons are tightly bound to the atom


Types of conductor:

there are different types of conductors available in electrical field. they are given below,

  1. Hard drawn copper conductor
  2. cadmium copper conductor
  3. steel core copper conductor
  4. copper welded conductor
  5. all aluminium conductor
  6. aluminium conductor steel reinforced(ACSR)
  7. smooth body ACSR
  8. expanded ACSR
