Conductors are materials that permit electrons to flow freely from particle to particle . ... If a charged conductor is touched to another object, the conductor can even transfer its charge to that object. The transfer of charge between objects occurs more readily if the second object is made of a conducting material.
What is conductor in science definition?
d(1) : a material or object that permits an electric current to flow easily Copper wire is a good conductor . — compare insulator, semiconductor. (2) : a material capable of transmitting another form of energy (such as heat or sound) Aluminum is a conductor of heat.
What is conductor short answer?
In physics and electrical engineering, a conductor is an object or type of material that allows the flow of charge (electrical current) in one or more directions. Materials made of metal are common electrical conductors.
What is an insulator in science?
Insulator, any of various substances that block or retard the flow of electrical or thermal currents . ... Different insulating and conducting materials are compared with each other in this regard by means of a material constant known as resistivity.
What are conductors in?
A conductor is a material which contains movable electric charges . In metallic conductors, such as copper or aluminum, the movable charged particles are electrons, though in other cases they can be ions or other positively charged species.

Who is called conductor?
A conductor is a material which electricity, heat or sound can flow through . An electrical conductor conducts electricity. The ability to conduct electricity is called electrical conductivity. Most metals, like iron and copper, are electrical conductors.
What are 3 types of conductors?
Many materials are used to transmit electrical energy, but those most frequently specified for types of conductors are copper, copper-covered steel, high strength copper alloys, and aluminum .
What are good conductors?
Most metals are considered to be good conductors of electrical current. Copper is just one of the more popular materials that is used for conductors. Other materials that are sometimes used as conductors are silver, gold, and aluminum. ... Aluminum and most other metals do not conduct electricity quite as good as copper.
What are 5 examples of insulators?
Examples of insulators include plastics, Styrofoam, paper, rubber, glass and dry air .
Is water an insulator?
Well actually, pure water is an excellent insulator and does not conduct electricity. The thing is, you won’t find any pure water in nature, so don’t mix electricity and water.
What is insulator and examples?
An insulator is a material whose internal electric charges do not flow freely . eg- plastics, Styrofoam, paper,rubber, glass and dry air .
What household items are conductors?
A good rule of thumb is that any metal object is a conductor. So in a house, you could find many conductors in a kitchen, for example pots and pans, forks, knives, and spoons. The metal coins in your wallet or purse are also conductors. Other metal conductors are jewelry, tools, wires, and pens.
Which is the bad conductor?
Materials that are poor conductors of electricity are called insulators . Some examples are wood, glass, plastics, non-metal elements that are polymers of hydrocarbons.
Which metal is the best conductor of electricity?
- Silver. The best conductor of electricity is pure silver, but to no surprise, it is not one of the most commonly used metals to conduct electricity. ...
- Copper. One of the most commonly used metals to conduct electricity is copper. ...
- Aluminum.
