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.
