what are conductors and insulators?

  • 1

In physics and electrical engineering, a conductor is a material which contains movable electric charges. In metallic conductors such as copper or aluminium, the movable charged particles are electrons.Insulators are non-conducting materials with few mobile charges and which support only insignificant electric currents.

An electrical insulator is a material whose internal elctric current do not flow freely, and which therefore does not conduct an electric current, under the influence of an electric current.

Conductors: Thermal conductivity is the property of material to conduct heat from it. Metals are good examples as they contain high concentration of free electrons. Substances having high thermal conductivity are conductors.
Examples: Copper, Gold, Iron, etc. metals are examples of conductors.
Metals: They are especially good conductors because they have free moving electrons which can carry the energy quicker and more efficiently, by vibration. Since these electrons are free to move, energy transfer takes place very quickly.
 
Insulators: A substances which is poor conductor of heat electricity are insulators. Insulators are poor conductors because of the lack of mobile (free) electrons.
Examples: Rock wool, Fiberglass, White pine, window glass etc.
These are bad conductors because of lack of free electrons. The specific heat of these substances is high, that means that you need more Joules (a measurement of energy, like calories) of heat to raise the temperature of one kilogram of substance by 1 degree Celsius. There specific heat values are much higher than the specific heat capacity of most common items, like metal. This means that metals conduct heat better because it takes less energy.

Conductor-Which produce heat,electricity etc.

Insulator-Which does not produce heat eletricity etc.

  • 0

The substances that conduct electricity are called Conductors.Substances that donot conduct electricity are called Insulators.

  • 0

The objects which let electricity pass through them are called conductors.

The objects which do not let electicity pass through them are called insulators.

  • 0

Conductors- They are the materials which allow the current to pass through them.

Insulaters- They are the materials which do not allow the current to pass through them.

Conductors and Insulators

 

In a conductor, electric current can flow freely, in an insulator it cannot. Metals such as copper typify conductors, while most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge through them. "Conductor" implies that the outer electrons of the atoms are loosely bound and free to move through the material. Most atoms hold on to their electrons tightly and are insulators. In copper, the valence electrons are essentially free and strongly repel each other. Any external influence which moves one of them will cause a repulsion of other electrons which propagates, "domino fashion" through the conductor.

Simply stated, most metals are good electrical conductors, most nonmetals are not. Metals are also generally good heat conductors while nonmetals are not.

conductor are those object which can pass current easily.

insulator are those object which doesn't pass current.

conductors pass electricity & insulators don't.

the materials that allow electric current to pass through them are called conductors. and the materials that do not allow electric current to pass through them are called insulators.

Hello Srajan, 

Conductors and Insulators

 

In a conductor, electric current can flow freely, in an insulator it cannot. Metals such as copper typify conductors, while most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge through them. "Conductor" implies that the outer electrons of the atoms are loosely bound and free to move through the material. Most atoms hold on to their electrons tightly and are insulators. In copper, the valence electrons are essentially free and strongly repel each other. Any external influence which moves one of them will cause a repulsion of other electrons which propagates, "domino fashion" through the conductor.

Simply stated, most metals are good electrical conductors, most nonmetals are not. Metals are also generally good heat conductors while nonmetals are not.

All the best in your studies
