Energy used for specific jobs

    One thing that is not discussed here is the energy used for specific jobs only power.  For example, refrigerators turn on and off. Therefore, a refrigerator that runs almost full time can be cooled with the same energy but at lower power than a cycle in which each cycle consumes more energy. Energy = Power for time. Secondly, all kinds of devices now use motors in inverters or other electronic devices that control the frequency or voltage, giving the motors only the speed and, therefore, the power needed to perform a specific job. On-demand water pumps come to mind and offer only the pressure and flow rate required and nothing more. Needless to say, the power required is only what is needed for that pressure and volume. So far, less energy is wasted. Apparently, the team that is discussing works according to this principle. But, whether DC is operated from rectified AC or inverted DC to Poly Phase AC, the specific design used is unknown.

INTERNATIONAL UNITS OF THE SYSTEM

S.I. UNITS  In an additional continuation of our theme mentioned above, the concept can often be easily accessible and comprehensible if we are familiar with the SI units of the physical quantity, Prefixes, symbols, values, symbols of Greek letters used in the unit. The complete knowledge of all this physical quantity helps us to understand the subject very clearly. Before entering the individual theme of the topic, let us familiarize ourselves with the physical quantities.  UNITS  The reference standard for measurement is called a unit. The measure of a physicist the quantity is necessary because, without it, we cannot study the characteristics of the problem. There are seven physical quantities, the length, the mass, the time, the electric current, the temperature, the intensity of the light and the amount of substance are Called fundamental physical quantities.  DERIVATIVE UNITS  All those units in physics, that is, derived from the units of length, mass, time, electric

The cons are more substantial than you say

    The disadvantages are more substantial than you say, the initial cost of a solar is not "moderately expensive". It is very expensive. Even with government subsidies and tax exemptions, it's still expensive. Just by making a lot of dubious assumptions about degradation, the escalation of the cost of energy, do solar energy providers manage to quote equilibrium times of 20 to 25 years? Without government subsidies and tax exemptions, it is a certain economic loss.      The cost has to be reduced to make solar energy really viable as an alternative for most environments. The fact that solar energy is useless most of the day is not an insignificant problem, especially because the part that is lost is the night when most houses need more electricity, not less. Factories and offices can make good use of solar energy during working hours, but that is not true for owners. And it is quite inefficient during the day in many areas, where heavy clouds or low sun angle limit t

SEMICONDUCTOR n-type

   when a small amount of pentavalent impurities is added to a pure semiconductor, it is known as an n-type semiconductor. The addition of pentavalent impurities produces a large number of free electrons in the semiconductor crystal, from the bonding diagram.  Since arsenic is a pentavalent element, the four valence electrons of germanium form a covalent bond with the arsenic atom and the electrons of the fifth valence are left free producing n-type conductors.  SEMICONDUCTOR p-type    When a small amount of trivalent impurities is added to a pure semiconductor, it is called p-type semiconductor. Such impurities that produce the p-type Semiconductor are known as acceptor impurities because the holes created can accept the electrons. The formation of the p-type semiconductor can be explained with the help of the connection diagram mentioned above.  When a small amount of trivalent impurities such as gallium is added to the pure germanium crystal, there is a large num

Difference between SSD and SSD card

  An SSD is a solid-state drive, or essentially a standard computer hard drive that uses semiconductors (instead of a spinning wheel and a reader's arm) to read or access the data. By "SSD card", you mean an external SD memory card or a chip. You can create a hidden copy of your HDD in an SDD. But as Whitson Gordon mentions in his Lifehack article of April 2013, that may not be your best option to transfer or clone your hard drive. Apparently, an SSD has less space to work than an HDD; If you are looking to migrate your drives without having to reinstall Windows, this is something you should consider. Relays     An easier approach would be to use relays. Faster for a beginner to visualize the contacts and how they change. The coil is direct. Mechanical contacts will handle an inductive load more easily (I know there are chunky semiconductors) without having to worry about exceeding the absolute maximum ratings of a device due to transients (we do not know how big t

DIODE AND ITS APPLICATION IN THE FIELD OF ELECTRONICS

   According to John Daltons, the atom of the atomic theory is the smallest particle of an element that is indivisible. Later, Bhor and Rutherford assigned a model for an atom and also altered the definition of an atom. An atom is the smallest particle of an element that can be divisible. The fundamental particles of an atom are electrons, protons, and neutrons. The electrons have a negative charge, the protons have a positive charge and the neutrons have a neutral charge. The electrons present in the outermost part of an atom are called Valence electrons or free electrons. It is these Valence electrons or free electrons that plays an important role in determining the given substance as conductors, insulators, and semiconductors. Semiconductors play an important role in the field of electrons. A semiconductor can be defined on the basis of its conductivity, resistivity, and atomic structure. There are two types of semiconductors (a) intrinsic semiconductors (b) extr

Electronsworklike

     Actually <Electronsworklike>Dominated. When you close a circuit with a potential difference on each side of the break (switch, unpolarized PN junction, etc.), then what happens is that an electron (for the sake of this argument) is released from its covalent bond with any type of material atom (driver) that we are discussing here.      Typically copper or silicon, in the case of a PN junction. That liberated electron is attracted to the most positive side of the circuit and crosses along its path until it collides with another atom and releases its valence electrons, and so on. This chain reaction is called 'electron current flow', that is. current that flows from negative to positive. Now that positive ion (that first atom that released the first electron) now has a positive charge, of course, and has a "hole" where the electron should be. The negatively charged electrons are attracted by this positive ion and will try to fill that "hole". T

ELECTRONICS AND ITS GROWTH

     Electronic Technology is moving so fast that new developments can be confusing for consumers to understand. The growth of Electronics leads to diverse applications in the field of Science and Technology, Medical Technology and Engineering. The various devices that are used for practical applications are Radio, Televisions, Computers, Telephones, Mobile phones, and other communication devices.     The growth of Electronics leads to diverse applications in the field of science and technology, medical technology, engineering and other communication devices. Since it is a field in development, additional researchers lead to many applications that are practically revolutionized, there is no limit to their development and they will continue forever. BASIC ON ELECTRONICS AND ITS GROWTH.      To understand the latest news on an electronic technology of the world, one must know the basic elements of electricity and electronics.     The basic definition of an Electronics

DIODE

    Unless their non-critical diodes are not generally used to provide a voltage drop, although they are frequently used for 'diode-O' 2 supplies together, or as mentioned elsewhere, they provide protection for reverse gear. For lower forward voltages, it is more common to use Schottky, which has a forward drop of 0.3 V or so. You usually do not use a high-value R to drop voltage unless you are working in very high voltage / low current applications. for rails below 5 V, a 0.7V drop is generally intolerable; although it can be insignificant in systems that use 12V or high. Again, your specific application. Zener can be used in both derivations and serial topologies, depending on what you try to do, but they are only used in low precision applications. It is quite common today in computer electronics to have secondary 1.2V supplies that can be maintained at a 5mV tolerance or change dynamically in steps of 5mV, such as the SVID rails on a CPU. Silicon Diode       The s

EMP PROTECTION

    Protection against vacuum I have been reading that diode junction is the weak link in electronics when they undergo an EMP. While transistor junctions would also be subject to failure, the idea is that diodes are often the guardians of adequate current flow in the power supply stages and elsewhere. the EMP would introduce high-voltage transients that could be high enough to exceed the diode's breakdown voltage, which in turn would allow the diode to temporarily conduct the current in the wrong direction until the transient EMP voltage breaks down. essentially, the process is equivalent to replacing the diodes with low-value resistors during the transient peak and during this time, although brief, it damages the sensitive components. This leads me to ask if there is a trade-off between the normal parameters for the selection of the diode/rectifier and the use of more robust diodes that are capable of handling higher forward and backward voltages. Of course, there are other fac

IR SENSOR

      IR sensor terrible yes, after a fashion It is rough and very out of focus, but IR that affects the filament will change its temperature and therefore it is the radiation of the black body and also its resistance.      The mass of the filament is huge for a sensor and is subject to the ambient temperature since the bulbs were not completely evacuated and the ambient temperature is an important contribution to the temperature of the filament in most cases that somehow would have to filter. basically, it ends up measuring only the ambient temperature of the filament. Then it is not a good sensor. The change is non-linear resistance to temperature and increases significantly when the filament is heated. This effect is necessary for the design to create the correct power. There are much better and more accurate ways to detect IR. I found infrared sensors of the type commonly used in the security light of home motion sensors online for a couple of dollars. The PIN diodes that are u

EDUCATION TECH

Electronics is no longer an exotic set of specialties    Many people play Scrabble, and these days some people pay any amount for the latest technological gadget.It would look like a regular Scrabble game, but inside the chips, there would be information that the board could read you play your chips, and the board automatically reads the word, calculates your score and adds it to your previous score - each player's score would be shown on the board for all to see.    If I wanted to challenge someone, I could press a challenge button, and the board would have the data of all the Scrabble words acceptable and not, if it was acceptable or not, and address the scores in this way they turned Battleship into an electronic battleship, I'm surprised it was not done with Scrabble.It used to be when you played bowling, you had to keep track of your score, now the electronics do it for you.    It's because electronics is no longer an exotic set of specialties.

How about a paradigm shift?

     A lesson from the past was better assimilated when notes were taken ... whether the notes were revised or not. The hand that moves to write connected the lesson to different parts of the brain. The brain thinks much faster than the speed of speech. Taking notes focuses additional thoughts on the interruption and cross-reference of lesson information. How can the computer be used?
