While a conductor transmits energy, an insulator slows or stops its passage. Some materials can be both a conductor and an insulator at the same time for different forms of energy. For example, most diamonds conduct heatexceptionally well, yet they are electrical insulators. Metals conduct heat, electricity, and sound.
Electrical conductors transmit electrical charge in one or more directions. Any charged particle may be transmitted, however, since electrons surround atoms, while protons are usually bound within the nucleus, it's much more common for electrons to move than protons. Either positive or negative charged ionsalso can transfer charge, as in seawater. ...
Most metals are also excellent thermal conductors. Thermal conductivity is heat transfer. This occurs when subatomic particles, atoms, or molecules gain kinetic energyand collide with each other. Thermal conduction always moves in the direction of highest to lowest heat (hot to cold) and depends not only on the nature of the material but also on th...
Transmission of sound through a material depends on the density of the matter because sound waves require a medium to travel. So, higher density substances are better sound conductors than low-density materials. A vacuum cannot transfer sound at all. Examples of good sound conductors include: 1. Lead 2. Steel 3. Concrete Examples of poor sound cond...
A conductor is a material that permits a flow of energy, such as electricity, heat, or sound. Learn the functions, differences, and examples of various types of conductors and insulators in science.

An electrical conductor is an object or material that allows the flow of charge (electric current) in one or more directions. Learn about the types, properties, and applications of conductors, as well as the factors that affect their resistance and conductance.
Sep 20, 2020 · Learn how to identify materials that conduct or resist different forms of energy, such as electricity, heat, and sound. See common examples of electrical, thermal, and acoustical conductors and insulators with explanations.
Aug 18, 2024 · Materials are classified as conductors, insulators, or semiconductors according to their electric conductivity. The classifications can be understood in atomic terms. Electrons in an atom can have only certain well-defined energies, and, depending on their energies, the electrons are said to occupy particular energy levels.
