When electric current flows through a metal wire?

Answer 1

Electrical current doesn't work quite the way that you would think.

A simple way to describe electrical current is to imagine a straw filled with marbles. Each marble represents an electron. If you push an electron in one end of the straw, and the straw was full, a marble would exit the other end of the straw.

However, while that example gives an idea of what is going on, electricity is actually exactly the opposite of that. An electron is "pulled" out of one end of a conductor, which crates an electron "hole". An electron next to the hole moves into that empty spot, and so on and so on. So, even though you could visualize the electricity moving through the conductor as "pushing a marble", it's really "pulling one out" and marbles are moving to "fill the gap". (This is known as hole movement in electricity).

Different metals have different levels of conductivity. The conductivity refers to how easily electrons can move through the metal. The less conductivity, the more "resistance" there is. When electrons are forced through a metal that has a high resistance, heat is generated. This is why the burner on your electric stove gets hot; a lot of electricity is being pushed through a metal that has a high resistance, and therefore gets hot.

The electric flow through Metal by the move of Electrons from one place in that Metal to another place.

Answer 2

current flows through the conductor due to the motion of the free charge carriers present in it. The more charge carriers present in the conductor, the more current flow through that conductor. No free carriers present in the insulator and hence no current flows through insulator. thus..free charge carriers causes the current flows through the conductor.

Answer 3

Current flows in a metal due to abundant free electrons present in it. metals being transition elements, have variable valancies due to which electrons in the valence shell can detach from the orbit. when there is a potential difference between the two ends, electrons flow from higher to lower(conventional current).

Answer 4

The flow of electric current through a metal wire results in the movement of electrons along the wire. This movement of electrons creates a magnetic field around the wire. The amount of current flowing through the wire and the material of the wire itself affect the strength of the magnetic field produced.

Answer 5

Current comes from charged particles. Current= voltage/resistance.

Answer 6

When electric current flows through a metal wire the circuit is said to be closed.
