Transformer

In the inductance, as we all know that a changing current produces a magnetic flux induces a voltage change into a coil. In this case the influence of a magnetic flux is changing and is owned by two or more different coils. Coil-coil adjacent took part called a flux along with the coupling together (mutually coupled). In circuits that have a trailer together, a stream that changes in one roll of electrical current in the coil produces voltage other scrolls in a trailer with it. Voltage electrical current is characterized by a mutual inductance (mutual inductance) contained between the coil-coil adjacent to each other. Inductance which together were not we think of as an element in a basic circuit because as we find out earlier, is always possible that these existing inductance representing the influence of mutual inductance, in a series with an equivalent circuit containing self inductance of the voltage sources and existing flows. A coil-coil system is arranged in connection with which rolled on a core called a transformer. Transformers are available in various types and sizes. In a radio receiver, television, and stereo equipment are often used to connect the various levels of reinforcement in the system. Transformer is used to raise or lower the voltage and to adjust the level of impedance in a power system and electronics. In a linear transformation, ie a transformer which consists of a coil-coil are linear, self inductance and mutual inductance is the combined properties of these linear transformations. Furthermore, we can find in a transformer has a store of energy and the properties associated with the impedance. Especially in the area of existing frequencies in the linear transformation, the frequency is very important because in every application of the transformer has an alternating current which is in a state fixed.

Ions Concept

The concept of the ion is a continuation of the continuous substances by the effects of Debye falkennegan wylen and alex, who lives on the circumstances. E = 10 ^ 5 v / cm. In this accretion is the result of the conductivity was observed (effect of Warren). In this accretion conductivity results from the fact that limited time (time off) is a form of pressure. Something about the atmosphere to form ions. In fact high, very fast exchange with the resulting loss at atmospheric pressure. Atmosphere did not have time to form and also can not slow down the ions. The result of this asymmetry is not visible and the conductivity are increase. For the same reason the addition of conductivity at high frequencies around 3 x 10 ^ 6 cms (dybye effects) / falkennegan. The transition ions on the instructions that it should have a very difficult motion at atmospheric pressure that can not be measured and will follow the movements of atoms are very difficult at atmospheric pressure and an increase conciliates. At high frequencies of both could be asymmetrical electropothic no results.

Molar conductivity of electrolyte, does not depend on the concentration of K appropriate if compared with the concentration of electrolytes. However, in practice, the molar conductivity berparsial against concentration. One reason is the number of ions in solution may not contain or proportional to the concentration of electrolytes. For example, the concentration of ions in weak acid solution depends on the acid concentration is complicated, and alloys that make up the concentration of the acid. Do not make double the existing number of ions. Both because the ions interact more strongly. Then the conductivity can not be proportional to the number of ions available. Measurement of the concentration dependence of molar conductivity showed the existence of two classes of electrolytes. General properties of the molar conductivity of electrolyte strength is only slightly decreases with increasing concentration. General properties of a weak electrolyte solution is a tool of the normal conductivity when the concentration approached or declined sharply to low values when the concentration increases. This classification depends on the solute and solvent used, for example lithium chloride which is a strong electrolyte in water. Strong electrolyte is a substance that perfect ionized in solution and includes ions.
