ELECTRIC PROPERTIES OF MATERIAL
- RESISTIVITY - IT IS THE CHARACTERISTIC PROPERTY OF THE MATERIAL OF WHICH THE CONDUCTOR IS MADE . IT IS THAT ELECTRICAL PROPERTY OF A MATERIAL DUE TO WHICH IT RESIST THE FLOW OF ELECTRICITY THROUGH IT.
- CONDUCTIVITY - IT IS THE RECIPROCAL OF ELECTRICAL RESISTIVITY . IT IS THAT PROPERTY OF A MATERIAL DUE TO WHICH THE ELECTRIC CURRENT FLOW THROUGH THE MATERIAL
- DIELECTRIC STRENGHT - IT MEANS THAT THE INSULATING CAPACITY OF A MATERIAL AGAINST HIGH VOLTAGE . IT IS AN INSULATION
- SUPER CONDUCTOR - IT REFERS TO PHENOMENON OF ABRUPT DROP OF RESISTIVITY OF SOME METAL AT A TEMPERATURE CALLED SUPER CONDUCTING TRANSITION TEMPERATURE BEFORE ABSOLUTE ZERO IS REACHED EXAMPLE THIS TRANSITION TEMP. IS 0.4 K FOR TITANIUM , 1.17 K FOR ALUMINIUM
