Parallel Magnetic Circuit

Parallel Magnetic Circuit: We have seen that a series magnetic circuit carries the same flux and the total mmf required to produce a given quantity of flux is the sum…

Magnetic Circuit Analysis

Magnetic Circuit Analysis: Magnetic Circuit Analysis - The presence of charges in space or in a medium creates an electric field, similarly the flow of current in a conductor sets…

Coefficient of Coupling

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…

Coupled Circuits Definition

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…

Generation of Three Phase Voltage

Generation of Three Phase Voltage: Three Phase Voltage can be generated in a stationary armature with a rotating field structure, or in a rotating armature with a stationary field as…

Polyphase System

Polyphase System: In an ac system it is possible to connect two or more number of individual circuits to a common polyphase source. Though it is possible to have any…
