What Is Electricity?

A simple question on a less than simple issue- what really is electricity ???
Behind burning lightbulbs and turning motors- I understand that deep down the road, science still cant explain how it really works .
Just moving electrons can't barely produce such a powerful stream of energy.
Are there any web-sites that explain how it is supposed to work -but in a more deeper consideration.

RE: What Is Electricity?

Think of electrons as water.

Therefore:

amperage = quantity
voltage = pressure
resistance = the resistance of the wire affect the quantity of electron flow, where you need more voltage to get the same amperage.

That is a very simple explanation.

Serioiusly, the description in the Wikipedia entry sums it up nicely in the first sentance.

Of course it can. What is your problem here?

The theory and engineering practice are quite consistent...

 Quoting AndesSMF (Reply 2):amperage = quantity voltage = pressure resistance = the resistance of the wire affect the quantity of electron flow, where you need more voltage to get the same amperage. That is a very simple explanation.

Its a good simplification - but only like 60% accurate.

Why not? just keep in mind the billions and billions and billions of electrons that are necesary..

Get the book 'A Short History of Nearly Everything' by Bill Bryson and read the section on electricity and also of atom and subatomic particles. He's the only writer who has been able to explain it in ways that a non-scientific layman like me can understand.

Brilliant book, by the way.

Reminds me of a joke... maybe you hear it...
So there'a an american, a syrian and a lebanese interviewed:

The american guy:
Rationing? What's that?
The lebanese guy:
Electricity? What's that?
The syrian guy:
Opinion??? What's that?

I think what you might be missing is the fact that electrons, and other charged particles, can release enormous amounts of energy when exposed to other charged particles. Meaning, the electromagnetic force between, say, two electrons (repelling) or a proton and an electron (attracting) is quite strong. So you basically make use of that potential energy.

It's all down to converting energy from one form to another. I mean, who would have thought that by controlled ignition of gasoline many times over, you'd be able to drive to the store and back?

So, what in electricity still remains as a mystery ?

RE: What Is Electricity?

I understand that Tesla has invented a way to transmit electric energy wireless -but the research-programs on this technology have been stalled under pressure from certain groups,who have an interest in maintaining the current way to consider the way electric energy is produced and distributed.
When I asked the initial question I of course know all about amps,volts,watts Ohm's law,condensators, coils,transformers etc.-I do have an engineering degree .
But i strongly believe there are certain details related to the inherent presence of electricity that are not all well understood.To me ,Tesla was a genius and he most likely was the one who knew most about electricity in his days.I wonder why nobody goes the step further and really invests large sums to pursue his philosophical way to considering the transmission,conversion and use of electric energy.
A link that gives a hint to those who have never heard about Tesla's ideas and inventions :

RE: What Is Electricity?

"Electricity
As mentioned in relation to atomic theory, electric charge is a complete mystery in today's science. Benjamin Franklin invented this concept as a useful model of observations, but never truly explained it. Two statically charged objects suspended from strings at a distance from each other will pull toward each other and remain angled toward each other against gravity indefinitely, as long as no external influence in the environment around them intervenes. There is no known power source supporting this endless effort, yet it is simply accepted as normal by today's scientists and educators. The new subatomic principle replaces this flawed concept with the proper understanding of electric charge observations, resolving the mystery of electric charge and electricity in general via the same basic principle that runs throughout the book.

The phenomenon of radio waves somehow emanating from oscillating electric charges in a wire is another completely unexplained facet of today's science. Electrons only carry a certain negative charge, which is unchanging -- that is the very definition of an electron. Yet, somehow these unchanging negative charged particles manage to "emit radio wave energy" as they oscillate. Precisely how this energy transformation happens in clear physical terms is completely unexplained, as is the emission of energy from electrons in an antenna wire whose individual charge never changes. Electrons are merely accelerated and decelerated repeatedly, driven to do so by the power source, while mysteriously transferring, transforming, and radiating radio wave energy. This mystery is resolved in clear physical terms by the new subatomic principle that runs throughout nature.

Magnetism
Magnetism is another mysterious and completely unexplained phenomenon in today's science. A block of wood will not cling to a refrigerator, yet a permanent magnet will. What is the difference? Magnetic energy, of course. So where is the power source for this energy that allows a heavy magnet to cling endlessly against gravity, and even hold other heavy objects as well? You won't find any answers in today's science -- only the same flawed "Work Function" explanation attempt offered for gravity"

Great and interesting information. For additional interesting reading, I always suggest the strange concepts of quantum theory.

Sometimes I believe that humans have this idea that we are so advanced as compared to xx years ago, and then you point out three things that we really have no idea about.

It's like stubborn medical doctors who still don't believe in Homeopathy because they don't see how the information is transported between the media and the patient.It relies on electromagnetic radiation stored in water.
Try to explain that to a rock-bottom scientist and he will laugh at you ,explaining that water does not have a memory.Yet it works !

Those effects are quite well understood nowadays, especially regarding the energetic relationships and conversions. The only things which are still being researched are quite a bit deeper down, but they don't relate to the actual effects as we're using them today all across our lives.

That weird article is apparently aimed at somehow convincing its readers that all science was bogus and nobody knew anything (and thus that their own particular weird claims were at least as good as science    ). I didn't dig deeper, but it appears to be a religious or similar site.

In short: electricity is about matter and its charge. The charge is a fundamental property. A moving charge creates a magnetic field, and vice versa. That can be used in to transform motion into energy, and v.v.

There aren't too many other candidates than electrons as wires carrying electricity keep their form when energy is transferred along them.
