Do you want to learn the difference between a conductor and insulator?
I will explain this here.
You will find conductors and insulators connected in most of the electrical circuits and overhead electrical power systems. Both have a different working role, properties, uses, and functions.
Difference between Conductor and Insulator
Here is an explanation for each of the difference in tabular form.
|1||Definition||The free electrons (or charge) flows in a definite direction through the conducting material or device. This conducting material or device called as a conductor.||The device through which electrical current does not flow is called as an insulator.|
(You can see these symbols used in many of the electrical circuit designs)
|The basic symbol of the Conductor:
||The basic symbol of an Insulator:|
|3||Formation||It is formed by metallic bonds.||It is formed by covalent bonds.|
|4||Basic Working Concept||When the conductor connects to other electrical power devices in the electrical circuit, it forms a closed circuit.
||When insulator connects to the other electrical power devices, the current will not flow in the circuit. This circuit works as an open circuit.
|5||Conductivity Property||It contains high electrical conductivity (so it carry more electrical power).||It contains low electrical conductivity.|
|6||Resistive Property||It has a low resistive property (low or negligible resistance).||It has a high resistive property.|
|7||Temperature Coefficient Property||It has a positive temperature coefficient of resistance. With the increase in resistance, the temperature also increases and vice versa.||It has a negative temperature coefficient of resistance. The resistance increase with the decreasing temperature and vice versa.|
|8||Protective Function||The conductor does not work as a protector.||An insulator is worked as a protector or protective device.|
|9||Different Types||The overhead conductor is classified into four different types.
1. All Aluminium Conductor (AAC)
|The insulator is classified into the following six different types.
1. Pin Insulator
|10||Materials Used and Example||Silver, Gold, Copper, Aluminium, Iron, Metal, etc. these are the types of conducting material used in the conductor.||Paper, Glass, Rubber, Mica, Porcelain, Wood, etc. these are the types of insulating material used in the insulator.|
|11||Protection||The live conductor protected by insulation wrapping like PVC (Polyvinyl Chloride).||There is no conducting material used in it so insulator does not require protection.|
|12||Used||It is used to carry current in electric circuits.||It is used to limit the current to the desired path.|
