About

You will be able to

  • Use Cartesian, cylindrical and spherical coordinates with gradient, divergence and curl
  • Find electric fields, potentials and capacitance using Coulomb's and Gauss's laws
  • Find magnetic fields using Biot-Savart and Ampere's laws and calculate inductance
  • State Maxwell's equations in point and integral form and apply boundary conditions
  • Analyse uniform plane wave propagation, skin depth and Poynting vector

Who it is for

  • B.Tech Electrical Engineering students of Semester 3 (AKTU)
  • Students of other universities studying the same subject who want unit-wise coaching

What you need

  • Engineering Physics and Mathematics (vector calculus)
  • Basic Electrical Engineering

Questions

Which syllabus does the Electromagnetic Field Theory course follow?

It follows the AKTU (Dr. A.P.J. Abdul Kalam Technical University, Lucknow) B.Tech syllabus for Electromagnetic Field Theory. If your own university's syllabus differs, the centre follows your university syllabus.

Will this help in the university examination?

Yes. Teaching is unit-wise as per the AKTU scheme, with numericals, previous-year question practice, MCQ tests and doubt sessions before the semester exam.

Is this subject very mathematical?

It uses vector calculus, so we begin with a short revision of coordinates, gradient, divergence and curl before the field topics.
