Ideal Transformer on Load: Transfer of energy from one circuit to another circuit through mutual induction is widely utilized in power systems. This purpose is served by Ideal Transformer on Load. Most often they transform energy at one voltage (or current) into energy at some other voltage (or current). A transformer is a static piece …
Coefficient of Coupling: The amount of coupling between the inductively coupled coils is expressed in terms of the coefficient of coupling, which is defined as where M = mutual inductance between the coils L1 = self inductance of the first coil, and L2 = self inductance of the second coil Coefficient of coupling is always …
Dot Convention in Coupled Circuits: Dot Convention in Coupled Circuits is used to establish the choice of correct sign for the mutually induced voltages in coupled circuits. Circular dot marks and/or special symbols are placed at one end of each of two coils which are mutually coupled to simplify the diagrammatic representation of the windings …
Mutual Inductance of Coupled Circuits: Mutual Inductance of Coupled Circuits – A voltage is induced in a coil when there is a time rate of change of current through it. The inductance parameter L, is defined in terms of the voltage across it and the time rate of change of current through it υ(t) = …
Coupled Circuits Definition: Two circuits are said to be ‘coupled’ when energy transfer takes place from one circuit to the other when one of the circuits is energized. There are many types of Coupled Circuits like conductive coupling as shown by the potential divider in Fig. 10.1(a), inductive or magnetic coupling as shown by a …
