Physical qualities such as malleability, phase, texture, colour, polarity, solubility, and others let us distinguish the components around us. However, as we all know, another major classification of elements is based on their electric charge conductivity, i.e. conductors and insulators.
If we make a simple experiment with a battery and a small LED bulb, we will find that the bulb does not light up when the electric circuit between the battery and the bulb is completed by plastic or cotton thread. When the same experiment is repeated with a metallic wire, such as copper, the bulb begins to glow. This means that some elements allow charge to be transferred from the battery to the bulbs while others do not. The electrical conductivity examples of such components is used to classify them. In this detailed post, we will learn more about conductors and insulators.

Conductor definition physics: An electrical conductor is described as material that allows electricity to flow freely through it. Conductivity is the property of conductors that allows them to conduct electricity.
The electric current is the flow of electrons in a conductor. Voltage is the force required to make that current flow through the conductor.

Insulator definition and Insulation meaning: A substance that doesn't conduct electricity well is an example of an insulator. A material or an object that does not easily allow heat, electricity, light, or sound to pass through it. Air, cloth and rubber are good electrical insulators; feathers and wool make good thermal insulators
The following are some examples of common insulators:

Definition of Electric Conductors
Electrical conductors, in their most basic description, are materials that allow electricity to flow freely through them. When we compare two types of materials, the first one is said to be a strong conductor of electricity because it allows electricity to move through it more easily.
The following are some examples of electrical conductors:
Electrical charges are easily passed through an electric conductor. Conductivity refers to conductor's ability to "conduct" electricity. These materials provide less "barrier" to the movement of charges. Conducting materials facilitate charge transfer by allowing electrons to freely travel through them.
A conductor has the following features when it is in equilibrium:
Many metals are excellent electrical conductors. The plastic covering that covers an electrical conductor is known as an insulator. This keeps us from getting electrocuted.
NCERT Physics Notes :
Sl. No. | CONDUCTORS | INSULATORS |
1. | A conductor is material that permits current to flow freely through it. | An insulator prevents current from flowing through it. |
2. | A conductor's thermal conductivity (heat allowance) is extremely high. | Insulators have an extremely low thermal conductivity. |
3. | A conductor's resistance is extremely low. | Insulator resistance is really high. |
4. | Conductors include copper, aluminium, and mercury. | Insulators include wood, paper, and ceramic. |
5. | Electrical equipment is made with conductors. | Electrical equipment is insulated with insulators for safety reasons. |
