# What is created when electric current flows in a conductor?

Contents

When an electric current flows in a conductor, it flows as a drift of free electrons in the metal. … Whenever there is a movement of electrons through a conductor, an electric current is created. Current can also be divided into two types- DC and AC.

## What is produced when current flows through a conductor?

Electromagnetism is produced when an electrical current flows through a simple conductor such as a length of wire or cable, and as current passes along the whole of the conductor then a magnetic field is created along the whole of the conductor.

## When an electric current is flowing through a conductor it?

An electric current flowing through a conductor produces magnetic field in its surrounding region.

## Which metal is the poor conductor of electricity?

Tungsten and Bismuth are metals which are poor conductors of electricity.

## What is flow of electrons called?

Electrons and Electricity

Electricity is the flow of electrons through a conductor, usually in the form of a wire, this flow is called an electric current.

## What is the relation between electric field and current density?

For an amazingly wide range of materials, an empirical rule called Ohm’s law gives the following relation between current density and applied electric field: J = σ E . In other words, the current density is directly proportional to the electric field.

## Which of the following is the best conductor?

Metals conduct electricity easily and the best conductor out of these are silver. The reason behind it is that in silver, there are electrons free to move than those in other elements which results in it to be the best conductor of electricity followed by Copper and Gold. Hence, option (D) is the correct option.

## Does same current flow in A conductor at all temperature?

So, the temperature of the conductor increases because of the current flow through it. So, we can say that when electric current flows through a conductor, the temperature of the conductor rises. Hence, the correct answer is option A.

## Which metal is best conductor of electricity?

What 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 are 4 poor conductors?

Non-metals are generally bad conductors or insulators. Metals, on the other hand, are good conductors. Some other examples of poor conductors of electricity are mica, paper, wood, glass, rubber, Teflon, etc. Some examples of poor conductors of heat are air, lead, etc.

## Is Aluminium a bad conductor of electricity?

Silver, gold, copper, and aluminium are materials with free electrons and make good conductors. Silver is the best conductor of electricity, followed by copper, gold, and aluminium. Hence, Aluminium is a good conductor of electricity.
