Description
This course is for those who are pursuing a bachelor's degree in electronics and communications engineering and is an advantage for them to get good knowledge and score well in the examinations.Nowadays, electromagnetics plays a vital role because of the advancements in technology. Electronic circuits and network circuits have the limitation that they only describe the voltage, current resistance, etc., but they cannot give the electric field intensity, attenuation constant, phase constant, lambda, or wavelength types of parameters. Therefore, network theory fails to give the above parameters. So electromagnetic field theory is the advancement of network theory.In this subject, you may know some fundamental concepts .Section 1: Deals about the the field, vector and scalar fields, unit vectors, position vectors ,distance vectors etc.,Section 2: Deals about the vector algebra, which includes the dot product rules, some basic formulas of vector algebra and vector calculus, the cork screw rule, and the vector scalar triple product and scalar triple product discussed elaborately, which are required for solving the problems in electromagnetic fields theory.Section 3 : This is all about the review of coordinate systems, which include the cartesian coordinate system or rectangular coordinate system, cylindrical coordinate system, and spherical coordinate system. Next, we discussed point transformations like rectangular to cylindrical or vice versa as well as cylindrical to spherical or vice versa. We also discussed what the DEL operator is, why it was used, and how these del operators are used for divergence, curl, and gradient operations with some sort of rule. Next we also discussed the statements and mathematical approach of divergence theorem, curl for stokes theorem etc., Section 4: Discussed Coulomb's law and vector form. Coulomb's law for n number of charges, electric field intensity, and finding the electric field intensity for different charge distributions like point charge, infinite line and sheet charge and volume charge, etc., also find the electric flux density from the electric field intensity formulas. next we discussed the gauss law and its applications Feel free to ask any doubt while learning the courseHappy learning!Skill Gems EducationPUDI V V S NARAYANA
