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.

∙ 14y agoElectrical 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.

∙ 15y agoCurrent 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).

What is electrical energy converted into when electric current flows through the metal filament of a light bulb?
Electrical energy is converted into light and heat when electric current flows through the metal filament of a light bulb.
When electric current flows through the metal filament of light bulb electric energy is converted to?
Heat and light.
What is an electric current through a metal?
It's flow of electrons under directing external electric field.
How electric iron become hot when electric current passes through it?
The electrons in the current have a lot of energy due to the tiny electric force on each one and the very large number of electrons involved. As they move from atom to atom in a metal conductor, some of this energy redistributes to the metal atoms. This energy causes the conductor atoms to move faster, which means they get hotter, and the heat flows to the surface of the iron.
What does the electric current have?
In metal conductors, electric current is the flow of electrons.
What is electrical energy converted into when electric current flows through the metal filament of a light bulb?
Electrical energy is converted into light and heat when electric current flows through the metal filament of a light bulb.
When electric current flows through the metal filament of light bulb electric energy is converted to?
Heat and light.
How an electric current is produced?
When charges (means charged bodies) move , then we say that an electric current is produced. If charges remain at rest, current is zero. If charge Q moves through a metal in time t , then current I through metal is: I=Q/t; moreever, electric current can also be produced by rate of change of magnetic field through a metal...,
A place of nonmagnetic metal that becomes magnetized when an electric current flows around it is called?
electromagnet
A piece of nonmagnetic metal that becomes magnetized when an electric current flows around it is called an?
electromagnet
A piece of nonmagnetic metal that becomes magnetized when an electric current flows around is called?
Electromagnet perhaps?
How does an electric current produce light?
By heating a metal wire called a filament. In a light bulb (lamp) the electric current flows through a tungsten filament which glows white hot giving off light.
What metal doesn't change when electricity goes through it?
Electric current is a flow of electric charge through a medium
What is an electric current through a metal?
It's flow of electrons under directing external electric field.
What do electro magnets do?
Electromagnets are basically coils with a metal core in them. If current flows through the coil they are magnetic, if there's no current flowing through it, it's not.
When electric energy flows through the metal filament of a light bulb energy is converted to?
Heat, which then produces light.
What property of metal is it when an electric current flows through metals?
to be honest, it depends on which metal. some could be conductors, some insulators. conductors would probably get hot, they may bend or snap and if you were to touch them you may get a shock. where as with insulators, they shouldn't go hot, there "insulators" of the electric current as it doesn't go through the metal. if im wrong im sorry! but im 14 and just learnt this in physics. :L hope this helps!
