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 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

   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

  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

   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

     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

     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

    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.
