Magnetic-core transformers are static devices containing magnetically coupled windings. They are used in power systems to change values of voltage and current at a single frequency. In communications circuits, often over a wide band of fiequencies, they are used to provide direct-current isolation, signal splitting and combining functions, specific current or voltage ratios, impedance matching, and phase inversion.


The Institute of Electrical and Electronics Engineers,Inc. (IEEE) has defined a transformer as follows: "A static device consisting of a winding, or two or more coupled windings, with or without a magnetic core, for introducing mutual coupling between circuits.
Note:Transformers are extensively used in electric power systems to transfer power by electromagnetic induction between circuits at the same frequency, usually with changed values of voltage and current.


Magnetic-core inductors and reactors are static devices containing one or more windings to introduce inductance into an electric circuit. Reactors are used in power circuits primarily to filter alternating current from direct current. Inductors are used in communications systems primarily in frequency-selective circuits.


In this chapter, only those devices having magnetic cores will be considered. The type of core material is known as soft magnetic material, which is defined as ferromagnetic material which, once having been magnetized, is very easily demagnetized (i.e., requires only a slight coercive force to remove the resultant magnetism).


A ferromagnetic material usually has relatively high values of specific permeability, and it exhibits hysteresis. The principal ferromagnetic materials are iron, nickel, cobalt, and certain of their alloys.

As the fastest growing demand of circuit and wiring diagram for automotive and electronics on internet based on different uses such as electronic hobbyists, students, technicians and engineers than we decided to provide free circuit and wiring diagram base on your needed.

To find circuit and wiring diagram now a day its easy. E-learning through internet as a right place to search an exact circuit and wiring diagram of your choice and it's much fun and knowledgable. On internet you will find thousands of electronic circuit diagrams some are very good designed and some are not. So you have to modify them to make them according to your needs but some circuits are ready to make and require no changes.

There are many categories of circuit and wiring diagrams like automotive, audio circuits, radio & RF circuits, power supply circuits, light circuits, telephone circuits, timer circuits, battery charger circuits etc. There are many types of circuit and wiring diagrams some are very easy to build and some are very complicated, some are so small and some contain huge list of parts.

We provides free best quality and good designed schematic diagrams our diagrams are free to use for all electronic hobbyists, students, technicians and engineers. We also provides a full educational system to students new to electronics.
