Electrical properties of Conducting Materials

Briefly describe the Electrical properties of Conducting Materials?

• Resistivity:  It is the measure of the resistance offered by a material having unit length and cross section area to electric conduction.

     A good conducting material, having resistivity must be low.

• Conductivity: It is indicate of the ease with which a material is capable of conducting electric current (charges/heat).

      A good conducting material, having high con ductility.

• Temperature Co-efficient of Resistance:  The change in resistance of a material per ohm per degree change in temperature is called Temperature Co-efficient of Resistance.

   This means that the change of resistance with change in temperature should be low.

• Contact Resistance:  It refers to the resistance of an interface between two conductors.
• Dielectric Strength:  It is the maximum electric field that a material can with stand without experiencing failure of its insulating properties.
• Electric energy dissipated in the form of heat must be low.
