Difference Between Conductor and Insulator

Hello, friends, I hope you all are doing great. In today’s tutorial, we will discuss the Difference Between Conductor and Insulator. The basic difference between conductor and insulator is that in conductor current can pass while in insulator current can not flow.

In today’s post we will have a detailed look at both conductor and insulator with the detailed compare them to find their differences. So let’s get started with Difference Between Conductor and Insulator.

Difference Between Conductor and Insulator

• The types of material that allow the flow of current is called a conductor.
• At the surface of the conductor electrical field is exist but in the conductor not exits.
• After the application of the magnetic field they store energy.

• The value of potential is constant at all points of a conductor.
• The thermal conductivity of the conductor is larger than the insulator.
• There is weak covalent bond exits in the conductor.
• Its conductivity is large.
• It offered less resistance than the insulator.
• Electrons in this substance can move freely.
• Its resistivity is not constant and changes from low value to high.
• The conductor has a positive temperature coefficient of resistance.
• The conduction band is completely filled with electrons.
• Its valance band is empty.
• There is no forbidden gap exits in the conductor.
• The examples of a conductor are Irons, aluminum, silver, copper,
• Its common applications are to creat electrical wires.

Insulator

• The category of material through which current can not pass.
• There is no existence of an electrical field in the insulator.
• When a magnetic field given it does not store energy.
• The potential across the insulator is 0.
• The thermal conductivity is less than the conductor.
• The high-value resistance is offered by the insulators.
• There is no free movement of electrons in the insualtor.
• The resistivity of the insulator is high.
• Insulators have a Negative temperature coefficient of resistance.
• The conduction band of the insulator is empty.
• The valance band of the insulator is filled.
• There is a large forbidden gap that exists in the insulators.
• Examples of insulators are Rubber, wood, Paper,

What is Conductor

• The substanes through which current can passes is called conductor. After application of potential electrons can move freely in the conductor.

• The conductivity of the conductor is in direct relation with the number of electrons exits in the conductor.
• There is no forbidden gap in the conductor due to the overlapping of the valance and conduction band.
• As the resistance of a conductor is less so electrons can easily move when voltage is given to them.
• Silver is the best conductor and other conductors are aluminum, mercury.

What is Insulator

• The substance through which current can not flow is called an insulator. There are strong covalent bond exits in the insulators so free electrons, not exits.
• The resistivity of insulators is very larger than the conductor.
• There are large forbidden gap exits in the insulators and so there is large energy needed for electrons to moves from valance band to the conduction band.
• Common examples of insulators are wood, paper, etc.

Comparison between Conductor and Insulator

• Such substance through them current can flow due to the existence of free electrons called conductor and in insulators current not flows.

• In the insulator electrical field is not exited while at the surface of the conductor’s field exits.
• Energy storage does not occur in the conductor after the application of the electric field and in insulators, the magnetic field is stored.
• Weak covalent bond exits in conductor while strong bond exits in insulators.
• After the application of potential difference, electrons can move freely in the conductor and not in insulators.
• Less resistance exits in the conductor and high in the insulators.
• The potential at insulators is 0 while it remains the same at the conductor.
• COnductos has a full conduction band and the insulator has an empty conduction band.
• In conductors no forbidden gap exits and in insulators forbidden gap exits.
