Transformer Basics and Transformer Principles This type of transformer is called an “Impedance Transformer” and is mainly used for impedance matching or the isolation of adjoining electrical circuits. The difference in voltage between the primary and the secondary windings is achieved by changing the number of coil turns in the primary winding ( N P ) compared to the number of coil turns on the secondary winding ( N S ). Transformer Circuits Georgia State University Circuit Equations:Transformer. The application of the voltage law to both primary and secondary circuits of a transformer gives: The transformer is the most common application of the concept of mutual inductance. In the transformer, the effect of the mutual inductance is to cause the primary ciruit to take more power from the electrical supply in response to an increased load on the secondary. Transformer A transformer is a passive electrical device that transfers electrical energy from one electrical circuit to one or more circuits. A varying current in any one coil of the transformer produces a varying magnetic flux, which, in turn, induces a varying electromotive force across any other coils wound around the same core. Electrical energy can be transferred between the (possibly many) coils, without a metallic connection between the two circuits. How to Build a Transformer Circuit A transformer is a very essential part for many types of circuits. Transformers allow for a lot of different functionality in a circuit.
