How does eletricity works?

Electricity surrounds us on all sides. For most people, modern life would be impossible without it. Here are some examples:
In all parts of the house, you probably find outlets where you can connect all kinds of appliances.
Most portable devices need batteries , which produce varying amounts of electricity depending on their size.
During a storm, massive "displacement" of electricity, commonly called lightning , are fired from the sky.
In a much smaller scale, you may get a shock from static electricity on dry winter days. It's easy to create electricity with sunlight using a solar cell or even create it from the chemical energy of hydrogen and oxygen using a fuel cell .

But what is electricity? Where it comes from and what you can do so many different things?

The electricity we get from power outlets and batteries can power all different kinds of devices.
Electric motors turn electricity into motion. Lamps , fluorescent lamps and LEDs (light emitting diodes) convert electricity into light . Computers turn electricity into information. Telephones turn electricity into communication. TVs turn electricity into moving pictures. Speakers turn electricity into sound waves. Stun guns turn electricity into pain. Toasters , hair dryers and heaters turn electricity into heat. Radios turn electricity into electromagnetic waves that can travel millions of miles. X-ray machines turn electricity into X-ray

It's hard to imagine modern people living without electricity . In the absence of electricity, we again use fireplaces for heat, wood stoves for cooking, candles for light, slide rules to make more complicated accounts and talk to long distance we are left with letters and postcards.

Electricity starts with electrons. Every atom contains one or more electrons. Electrons have a negative charge. In many materials, the electrons are tightly bound to atoms: wood, glass, plastic, ceramic, air, cotton, all are examples. Since the electrons do not move, these materials can not conduct electricity. They are what we call insulators.

Moreover, most metals have electrons that can be separated from their atoms and move. These are called free electrons. Gold, silver, copper, iron and aluminum, among others, have free electrons. They help the electricity to flow through these materials, which are known as electrical conductors for conducting electricity.  The moving electrons transmit electrical energy from one point to another.

Electricity needs a conductor to move. Just as you need something to make it flow through the conductor. One way to make electricity is conducted is to use a generator. The generator uses a magnet to get electrons moving. There is a connection between electricity and magnetism. If you leave the electrons move through a wire, they create a magnetic field around it. Similarly, if you move a magnet near a wire, the magnetic field will cause electrons to move her. A generator is a simple device that moves a magnet near a wire to create a steady flow of electrons. A simple way to think of a generator is to imagine it acting like a water pump. Instead of water, the generator uses a magnet to produce electrons. This is an oversimplification, but a useful analogy.

There are two things that a pump can do with water: (1) Moving a number of water molecules. (2) Applying a certain pressure on the water molecules.

Likewise, the magnet in a generator can: (1) Push a certain number of electrons. (2) Apply some "pressure" on the electrons.

In an electrical circuit, the number of moving electrons is called the amperage or current, which is measured in amperes. The "pressure" on the electrons is called voltage and is measured in volts. So you might hear someone say: "If you spin this generator at 1,000 rpm, can produce 1 amp at 6 volts."

One ampere is the number of electrons moving (1 amp physically means that 6.24 x 10 18 electrons moving through a wire every second). The voltage, in turn, the amount of pressure on these electrons. Electrical circuits Whether you are using a battery, a fuel cell or a solar cell to produce electricity, there are three things that remain the same:

The source of electricity will have two terminals, one positive and one negative. The source of electricity (even as a generator, battery, etc..) Will try to push electrons out of its negative terminal at a certain voltage. For example, a AA cell at 1.5 volts to push electrons. The flow of electrons have negative terminal to the positive terminal through a copper wire or other conductor. When there is a path that goes from negative to positive terminal, there is a circuit and electrons can flow through the wire.

You can connect a device of any kind (a bulb , a motor , a TV , etc..) in the middle of the circuit. The electricity supply will provide power to the device and this, in turn, will make your work (create light, spin a shaft, generating images, etc..).

Electrical circuits can be quite complex. But you always have a source of electricity (a battery, etc..), A device (lamp, motor, etc..), And two wires to carry electricity between the battery and the device. Electrons move from the source to the device, and again back to the source. Moving electrons have energy. And moving from one point to another, they can do work.

In an incandescent lamp , for example, the energy of electrons is used for heat generation and heat creates light. In an electric motor , the energy of electrons creates a magnetic field and this field can interact with other magnets (for magnetic attraction and repulsion) to create movement. Each electrical appliance harnesses the energy of electrons in some way to create a useful side effect.

What is a volt?

Voltage is the difference in electric potential between two points. Its unit of measure is volts , named after the Italian physicist Alessandro Volta .

By analogy, the voltage would be the " force "responsible for the movement of electrons. The electric potential measures the force that an electric charge experiences within an electric field , expressed by Coulomb's law .

So the tension is the tendency that a load has to go from one point to another. Typically, it becomes a point which is considered equal to zero voltage and measures the voltage from the rest of the points on this.

To facilitate the understanding of electrical voltage can make an analogy between this and the hydraulic pressure . The higher the hydraulic pressure difference between two points, the greater flow, where there is communication between these two points.

By phasor method , alternating current, all variables in the equation are complex . Impedance is, in addition to resistance to passage of electric current, also the angular displacement of the waveform produced by the equipment ( capacitors and coils or inductors ).
