- The process of electrical current flowing through a wire is called conduction, and materials which conduct are called conductors. Most metals are good electrical conductors. Electrical cables are made from the metal copper.

Usually, electrical conductors have loosely bound electrons. Most metals are excellent electric conductors. The element that is the best electrical conductor is silver. Liquids that contain ions also conduct electricity. These include salt solutions, acids, and bases. 1. Silver 2. Copper 3. Gold 4. Aluminum foil 5. Graphite 6. Steel 7. Bronze 8. Br...
Most organic materials are electric insulators because electrons aren’t as free to move in covalent bonds. Sea water contains ions and conducts electricity, but pure water is an electric insulator. Some elements are either conductors or insulators, depending on their form or allotrope. For example, carbon is either a conductor or an insulator. Grap...
Most metals conduct heatas well as electricity. But, electrical and thermal conductivity don’t always go hand-in-hand. For example, diamond is an electric insulator, but an excellent thermal conductor. Crystalline materials often conduct heat. 1. Silver 2. Gold 3. Copper 4. Diamond 5. Stainless steel 6. Aluminum 7. Beryllium oxide 8. Mica 9. Carbon...
Thermal insulators resist the flow of heat. Building and clothing materials are often insulators. Although you might expect glass to be a thermal conductor, it’s actually an insulator. Thermal insulators either contain open space in their structure or else their atoms and molecules are irregularly arranged. 1. Water 2. Polystyrene foam 3. Plastic 4...

Conductors are materials which allow electrical current to flow through them easily. Metals are generally good electrical conductors. Insulators are materials which are poor...
I can explain the difference between electrical conductors and insulators and can identify where each type of material should be used.
Key Concepts: Definition of conductors in the context of science. Characteristics of conductors. Examples of common conductors. Importance of conductors in everyday life. Study Tips: Review the concept of electric charge and the movement of electrons in materials. Explore real-world examples of conductors and their applications.
A conductor is a material that allows electricity to flow through it. An insulator is a material that electricity cannot flow through. To determine whether an object is a conductor or insulator, you can build a simple circuit with a battery, light bulb, and three pieces of wire. Touch the free ends of the wire to the object you are testing.
