Around 600 BC Greeks found that by rubbing an 'electron' (a hard Fossilised resin that today is known as Amber) against a fur cloth, it would attract particles of straw. This strange effect remained a mystery for over 2000 years, until, around AD 1600, Dr William Gilbert investigated the reactions of amber and magnets and first recorded the word 'Electric' in a report on the theory of magnetism.

Electricity is produced when an electron moves after being taken away from an atom. Atoms are usually electrically balanced, there are as many positive charges (protons) as there are negative charges (electrons). Particles with the same charge repel or push each other apart. Electrons repel electrons; protons repel protons. Particles with the opposite charges attract each other. However, when the electrons leave and move together it produces electricity. When this electricity is controlled, it is called current electricity, when it can't be controlled it is called static electricity.

Electrons create energy that we refer to as electricity. Electrons are easy to remove from an atom, unlike protons and neutrons.
Electricity and magnetism are related and are the components of electromagnetism. Light is a subset of the electromagnetic wave spectrum. The electromagnetic wave spectrum also includes radio waves, microwaves, ultra violet rays, x-rays, and gamma rays. Magnets exhibit both attractive and repulsive forces. North attracts south, north repels north, and south repels south.

Magnetism and electricity are related. Both magnetism and electricity have opposites. In magnets north repels north and south repels south, but north attracts south. In electricity when you hook up positive and negative electrodes the electrons flow creating current electricity.

The Greeks discovered static electricity by rubbing things with amber.

When the great bang disturbed the soup of strings - energy morph in to different aspect of the same thing - one version is electricity - so electricity has to be billions of years old.

every matter is composed by very small parts, scientists name them atoms. Now, these atoms consist of even smaller parts, like neutrons, protons and electrons. As their name suggests, the electrons cause electricity, which is basically constant current of these extremely small parts along electric wires...In that sense one might say, electricity is generated within the substance of the matter itself...

the transfer of electrons from positive electode to negative electrode are the main cause of electricity because like every thing electrons also flow from high potential to low potential the move ment of electrons cause production of electricity

A complex and random evolution over thousands of years from a spark.

No doubt some Bright Spark came up with it. : )

THE SUN. All energy comes from the sun it is however converted to various forms by man.

When 2 pieces of amber were rubbed together it made a spark.

it is due to d flow of charges due 2 potential difference between 2 points
