Electricity and Magnetism ⚡🧲

📋 Course Details

The end-semester examination will be of 35 marks and 3 hours duration.
The question paper will consist of three sections: A, B, and C.
Sections A and B: Five questions each, with each question carrying 6 marks.
Section C: Compulsory section with 11 short-answer questions covering the entire syllabus.

Students are required to attempt four questions in total from Sections A and B, selecting two questions from each section.
Section C is compulsory.
Use of scientific calculator is allowed.

Vector Calculus: Gradient, divergence, curl, and their physical significance. Electric field due to a dipole, line charge, and sheet of charge. Electric flux and Gauss's Law with applications. Differential form of Gauss's Law, Green's theorem. 📏
Electrostatics: Potential difference, line integral of the electric field, potential due to point charges, dipole, quadrupole, and arbitrary charge distributions. Stokes' theorem in electrostatics, curl E = 0. Calculation of electric field (E) from scalar potential. 🌠
