DefinitionMaterial which permits the electric current or heat to pass through it Restrict the electric current or heat to pass through it.
Electric Field Exist on the surface but remain zero inside the conductor. Exists in the insulator.
Magnetic Field Stores energyDoesn't Stores energy
Potentialremains same on all points of the conductorNot same at all points
Conductivity Very HighLow
ResistanceLowHigh
ExampleIrons, aluminum, silver, copper, etc. Rubber, Wood, Paper, etc.
Application For making electrical wires and conductor As insulation in electrical cables or conductor, for supporting electrical equipment, etc.
