1. what is the difference between a good conductor and a good insulator?
152687
The most common difference between the two is that while conductors allow free flow of electrons from one atom to another, insulators restrict free flow of electrons. ... Conductors allow electrical energy to pass through them, whereas insulators do not allow electrical energy to pass through them.

Most metals are good conductors of heat. ... The reason that metals are good conductors of electricity and heat is due to the nature of the metallic bonds in metals, and the behavior of valence shell electrons in metal atoms.

There are different types of conductors and insulators because there are different forms of energy. Materials that conduct electrons, protons, or ions are electrical conductors. ... Usually, electrical conductors have loosely bound electrons. Materials that conduct heat are thermal conductors.

The material which stores the electrical energy in an electric field is known as the dielectric material, whereas the material which blocks the flow of electrons is known as the insulators. ... The dielectric material stores the electric charges, whereas the insulator block the electric charges.

Properties of metals they are electrical conductors because their delocalised electrons carry electrical charge through the metal. they are good conductors of thermal energy because their delocalised electrons transfer energy.

When electricity is applied to the metal, ions start to migrate from one end to the other end of the metal, but it is not possible for electrons to travel freely in glass in which electrons are tightly bound. This makes metal a good electric conductor.

Resistors. ... A conductor has low resistance, while an insulator has much higher resistance. Devices called resistors let us introduce precisely controlled amounts of resistance into electrical circuits.

The particles in an ionic compound are held together because there are oppositely charged particles that are attracted to one another. ... are hard because particles cannot easily slide past one another. are good insulators because there are no free electrons or ions (unless dissolved or melted).

Metals are good conductors of heat because of following two reasons : a) Metal ions are closely packed in the metal lattice and thus the transfer of heat from one end to another is more efficient. b) Availability of free electrons makes transfer of heat easier making it a good conductor of heat.

Good conductors are those materials which allow electricity to pass through them easily. Bad conductors are those materials which do not allow electricity to pass through them easily.

Examples of Conductors and Insulators Examples of conductors include metals, aqueous solutions of salts (i.e., ionic compounds dissolved in water), graphite, and the human body. Examples of insulators include plastics, Styrofoam, paper, rubber, glass and dry air.

Cotton is a good heat insulator, provided that it is NOT IN VACUUM. First of all, please understand the fact that air is a very poor heat conductor. ... Cotton is made of loosely intertwined fibers, and between them a lot of air is trapped. This explains why cotton is a good heat insulator.

The most significant difference between the static and current electricity is that in static electricity the charges are at rest and they are accumulating on the surface of the insulator. Whereas in current electricity the electrons are moving inside the conductor.

The term insulator is generally used to indicate electrical obstruction while the term dielectric is used to indicate the energy storing capacity of the material (by means of polarization). A common example of a dielectric is the electrically insulating material between the metallic plates of a capacitor.

Metals are lustrous, malleable, ductile, good conductors of heat and electricity. Other properties include: ... Valency: Metals have 1 to 3 electrons in the outermost shell of their atoms. Conduction: Metals are good conductors because they have free electrons.
