The most effective electrical conductors are: Silver. Gold. Copper.
What is an example of electrical conductor?
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.
Which is the best example of an electrical conductor?
Examples of Conductors
- Material such as silver is the best conductor of electricity. …
- Copper, Brass, Steel, Gold, and Aluminium are good conductors of electricity. …
- Mercury is an excellent liquid conductor. …
- Gases are not good conductors of electricity because the atoms are quite far away.
What does good conductor of electricity?
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. Example – Copper, Aluminium. Example – Rubber, Wood. Can be used to make electric circuits.
Which of the following is the best example of an electrical insulator *?
The most effective electrical insulators are: Rubber. Glass. Pure water.
What are some examples of good conductors?
What is conductor in electrical engineering?
In physics and electrical engineering, a conductor is an object or type of material that allows the flow of charge (electric current) in one or more directions. Materials made of metal are common electrical conductors.
What is conductor and types of conductor?
For example, graphite is a good conductor of electricity. … Some metals like copper, iron, silver, aluminium and gold are good conductors of electricity and are used widely. Though gold and silver metals are very good conductors bur are costlier than copper and aluminium.
Which of the following is the electrical insulator?
Solution: Metals are generally good conductors of electricity. So, Gold and Aluminium are good conductors of electricity. Non-metals are poor conductors of electricity. So rubber, being a non-metal, is an electrical insulator and hence a poor conductor of electricity.
Which of the following would be the best insulator?
Plastics and rubber are usually good insulators. It is for this reason that electrical wires are coated to make them more safe to handle. Metals, on the other hand, usually make good conductors. In fact, copper is used in most electrical wires and circuit boards for this reason.
Which of the following is an insulator of electricity?
Some common insulator materials are glass, plastic, rubber, air, and wood. Insulators are used to protect us from the dangerous effects of electricity flowing through conductors. Sometimes the voltage in an electrical circuit can be quite high and dangerous.
