I bet you are right now surrounded by the web of copper in our lives these days. Yea I'm talking about wires wires are used in literally everything that uses electricity though when you get down to it very few people understand what is actually going on in these copper tubes. To put it very simply it is a electrons game of leapfrog electronics is just the electrons moving from one atom to another.
Where does the power come from? Well your not really using electrons electricity can be easily explained with the parallel of a hose. If you are trying to spin a wheel with water are you using the water itself or the energy that is contained within the water? To be honest if you said the your moving the wheel with the water your both right and wrong. The water is simply a force carrier but your spinning the wheel with the energy that is transferred from the water.
Electrons are really just electromagnetic force carriers. Where does the energy come from well the electromagnetic force comes from copper intersecting lines of magnetic flux the magnets act like rotors in a pump though actually its kinda also not quite right to think of it like that.
That is really the basics of electrical generation though a rather cumbersome way of explaining it.
Though your probably wondering what goes on in those little copper tunnels that travel around you. Well the ones in your house that you plug your appliances into they are just a standard AC voltage either 240V 110V or somewhere in between depending on your country and have a frequency of either 50Hz or 60Hz. The other ones say for example the ones in your cellphone carry a series of pulses of electricity known as a bit this is either a +5V or a 0V signal a +5V is a 1 and the 0V is well a 0, Sound familiar? Yea I am talking about binary this is a very simple concept however to explain more would delve into digital electronics theory. how about those little white wires that go from your music player to your ears? those little wires don't carry pulses they carry waves of electricity that exactly match the sound waves that are intended to be produced. If I got an oscilloscope and measured the signals then ran them through a computer it would give me the same result.
So as you can see these little copper tunnels do a fair bit for you have a look around and thank the little electrons for their work.
