All We Know The Meaning Of 'Direct Current' Y 'AC'

We learned how solar cells work Solar Panel, how come the 'photon' with sunlight and are distributed in layers of solar cells to generate electricity.

It is also important to deepen the concepts of power and structure of matter, to understand better the work of the "Photovoltaic Systems' or 'solar modules' also called' solar panels'.

The positive electrical charges tend to move points from highest to lowest potential.

Therefore, by linking two drivers who are at different potentials, there is a movement of positive charges from the positive or negative greatest potential whose potential is lower. This movement of charges is called electric current.

Then you can define the concept of potential difference as the work required to bring a unit positive charge between two points.

The unit of potential difference is the volt (V).

In metals, electrical current is based on the presence of "free" electrons, ie negative charges. Normally, these electrons move between the metal atoms in a disorderly manner, but the difference of potential, are forced to move in one direction, resulting in electrical current.

There are two types of current:

1 .- Continuous Current

It is precisely when the charges flowing in the same direction. It is the type of current produced by batteries. Any small or large battery for home use and work with current cars like light bulbs.

2 .- AC

When circulating the above charges as a sinusoidal AC voltage and frequency with certain advantages in power transmission.

This case all devices and appliances that are plugged operate with this type of current. Their charges are as fast as a sense of another. Is this madness of electron charges and what they do give more strength and energy work.

In most countries of the world, is 110V AC and 220 V at a frequency of 60 and 50 Hz (Hertz). P. ahem. 60 or 50 cycles and 100 changes of direction of current in a second, is fabulous!

A stereo system, computer, washing machine, ironing clothes, blender, color television, dishwasher, dryer, stereo system, VCR, VCRs, coffee makers, microwaves, garage door, intercom doorbells, etc.. are among the many who work with alternating current.

Each team, machine, appliance mentioned have their own power. That is, each one works with a certain amount of Watt that is known as "load".

This concept is good to consider because it is used at all times and in all places when outputting the manufacture, assembly and installation of photovoltaic solar modules.
