Energy Density Formula in Magnetic Circuit: The Energy Density Formula of transformers, ac machines and several other electromagnetic devices are excited from ac rather than dc sources. With ac operation, inductance is effective even in…
Magnetically Induced Emf and Force: Magnetically Induced Emf and Force - Faraday's law of induction, which is the integral form of the fourth Maxwell's equation, is given as The integrated form of Eq.(2.15) for a…
Magnetic Properties of Materials: Magnetic Properties of Materials - From the magnetic point of view a material is classified according to the nature of its relative permeability (μr). All nonmagnetic materials are classified as paramagnetic…
Magnetic Circuit Calculations: Normally magnetic circuit calculations involve two types of problems. In the first type of problem it is required to determine the excitation (mmf) needed to establish a desired flux or flux density…
BH Curve Relationship (Magnetization Characteristic) for Ferromagnetic Material: In free space (also nonmagnetic materials), the permeability μ0 is constant so that BH Curve Relationship is linear. This, however, is not the case with ferromagnetic materials used…
Magnetic Field Equation: The exact description of the Magnetic Field Equation Basics is given by the Maxwell's equations and the constitutive relationship of the medium in which the field is established. Such description apart from…
Integrated Circuits Classification: Depending upon the functional utility, the Integrated Circuits Classification are classified as linear ICs and digital ICs. From the point of view of structural considerations, ICs can be divided as monolithic ICs,…
Integrated Circuit Definition: Integrated Circuit Definition referred as microelectronics, is the result of continued improvements in the characteristics and miniaturizations employed in solid state devices and components. So we can call integrated electronics as logical…
Environmental Aspects Of Generation of Electrical Energy: Conversion of one form of energy or another to electrical form has unwanted side effects and the pollutants generated in the process have to be disposed off. Pollutants…
Distributed and Dispersed Generation: Distributed Generation (DG) using many small generators of 2-50 MW output, installed at various strategic points throughout the area, so that each provides power to a small number of consumers nearby.…
