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 reaction takes place when an electric current is passes through water?
decomposition
When an electric current passes through water it causes the water to start to combust?
no, when an eletric current passes through water, it causes the water to start to decompose into hydrogen and oxygen
When a current flows through an electric bell what will happen to the armature?
When current passes through an electric bell, the armature gets magnetised and attracts the gong hence ringing the bell.
Why do electric cells have 2 terminals?
to form an electric circuit two terminals are required it is being closed and electric current passes through it .
Name two gaseous elements produced when an electric current passes through acidified water?
hydrogen and oxygen
What does a coil do?
Produce a magnetic field as electric current passes through it.
What will happen to an electric wire if a large current passes through it?
It will get hot.
What happen when electric current passes through acidified water?
when electric current is passed through acidified water hydrogen gas is released at the cathode..
When an electric current passes through water what new substances form?
whe n a eletric current passes through water what new substance forms
What is the meaning of cathode?
The part of a voltaic battery by which the electric current leaves substances through which it passes, or the surface at which the electric current passes out of the electrolyte; the negative pole; -- opposed to anode.
What reaction takes place when an electric current is passes through water?
decomposition
What electric current passes easily through?
good conductors like metals
When a current passes through a resistance what is the electric energy that is lost?
Becomes heat.

What happen to an electric current after it passes through each bulb?
There is a piece of filament in every light bulb, which has so much friction that when the electric current passes through it, heat energy is produced. This heat energy is then converted to light energy.
