Conductors

are materials that electrical current can easily pass through.

What does electric current pass easily through?

Electricity can pass through some objects better than through others.

Conductors

are materials through which electrons can travel more freely. Copper, aluminium, steel and other metals are good conductors. So are some liquids like saltwater.

What materials can electricity not pass through?

Materials that do not let current flow easily are called

insulators

. Most nonmetal materials such as plastic, wood and rubber are insulators.

What are 5 good conductors?

  • Silver.
  • Gold.
  • Copper.
  • Aluminum.
  • Mercury.
  • Steel.
  • Iron.
  • Seawater.

Which materials would the electric current pass through?

Materials that allow electricity to pass through them are called

conductors

. Copper wire is a good conductor. Materials that do not allow electricity to pass through them are called insulators. Plastic is a good insulator.

What are 5 insulators?

  • glass.
  • rubber.
  • oil.
  • asphalt.
  • fiberglass.
  • porcelain.
  • ceramic.
  • quartz.

What is a path that an electric current flow?


An electric circuit

is a pathway through which electric current flows. Now you know that electric current flows through a path called a circuit. You also know that a continuous electric current needs an energy source such as a battery.

What does an electric circuit always need for electricity to flow around it?

To produce an electric current, three things are needed:

a supply of electric charges (electrons) which are free to flow

, some form of push to move the charges through the circuit and a pathway to carry the charges. The pathway to carry the charges is usually a copper wire.

Which of the following is most likely to conduct electricity the fastest?


Silver

has the highest electrical conductivity of all metals. In fact, silver defines conductivity – all other metals are compared against it. On a scale of 0 to 100, silver ranks 100, with copper at 97 and gold at 76.

Does wearing rubber gloves prevent electric shock?

Selected properly,

insulating rubber gloves will do the job of protecting the worker against electrical shock

. Do not forget about leather protectors, for they are an essential part of wearing and using the insulating rubber gloves correctly.

Which metal is poorest conductor of electricity?


Bismuth and tungsten

are two metals which are poor conductors of electricity.

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.

What is the strongest conductor?


Silver

.

Silver

is the strongest conductor out of all known materials.

What are 4 examples of insulators?

Examples of insulators include

plastics, Styrofoam, paper, rubber, glass and dry air

.

What are 2 insulators?


Plastic, wood, glass and rubber

are good electrical insulators. That is why they are used to cover materials that carry electricity.

Is gold an insulator?

Gold is

a poor insulator

and a good conductor, having a resistivity of 22.4 billionths of an ohm-meter. As with lead, gold is widely used to make electronic contacts. Unlike many other metals, it is very chemically stable and resists the corrosion that degrades other types of electrical connectors.
