Do any of you guys know what electricity is?

Question

If so please explain theorly, and precisely. I need urgent help, so pls. answer. Thanks!

Answer 1

Electricity is the flow of electrons through a conductor.Movement of electrons.The voltage is the pressure that push the electrons through a conductor.When you throw a ball your hand is the voltage because is the force that push the ball,the ball is the ''electricity'' and the wind is the resistance.

Answer 2

It is basically the flow of electrons. In an electric wire, say copper, an electron enters the wire at one end. Copper will 'let go' of electrons quite easily, so it pushes an electron of copper over and displaces it. Think of a long bench full of football players sitting on it. Then the biggest guy comes over and forces his way to the first space. He pushes that guy into the next, into the next, etc, until the last guy on the bench gets pushed of of the bench. The displaced electron will do the same to the next copper electron, and on down the line. When the last copper electron is force over with nowhere to go, it is forced out of the wire. Which will enter your hand if you are holding it and give you a shock as the flow of electrons passes thru you!
In solid conductive metal, with no external forces applied, there exists a random motion of "mobile" or "free" electrons created by the thermal energy which the electrons have gained from the surrounding medium. When a metal atom contributes a free electron, it acquires a net positive charge. The population of freed electrons form a "charge-gas" or "sea of charge" which remains bound to the ion lattice by attraction, while the metal as a whole remains neutral. Metal atoms typically contribute either one or two electrons to the "sea." Free electrons can move amongst these positive ions, while the positive ions can only oscillate about their mean fixed positions. Electrons move, but the net flow of charge remains zero: given an imaginary plane through which the wire passes, the number of electrons moving from one side to the other in any period of time is exactly equal to the number passing in the opposite direction.

Answer 3

Electricity is a subdivision of the science of physics, and is a fundamental natural physical phenomenon seen in the attractions and repulsions of oppositely charged objects. It can be utilized as a source of energy in the form of a current. In its briefest definition, it could be called "the study of charge".

Electricity and magnetism are interrelated; it's virtually impossible to have one without the other.

Electricity is not the "flow of electrons" ... electrons don't move. They vibrate a bit, but they don't move in the sense that they go from Point A to Point B. What does occur, though, is that the wiggling of the electron allows a smaller particle (known as a photon) to pass from a higher potential point to a lower potential point. Potential can also be referred to as voltage, or the driving force behind electricity.

The rate of flow of charge is called current. The relationship between force (voltage) and flow (current) can be summed up in Ohm's Law which states that Voltage = Current * Resistance.

Several other laws cover what happens in and around electricity; they can be summed up as Maxwell's Equations. These four equations basically describe how electric and magnetic fields interact.

There's a lot more involved with electricity than this, but it should be enough to get you started.

Answer 4

I know I've let an electric fart when I can feel the juice running down my leg.
