EMF(Electromagnetic Field Theory), Mid-1 Previous year Question paper, R23 regulation

   EMF MID-1 Previous year  Question paper R23 regulation 

  Hi, here we have the EMF Mid-1 PYQ (Previous Year Question Paper). The Mid-1 exam mainly focuses on two units:

➤ Vector Analysis
➤ Conductors, Dielectrics, and Capacitance

Now, let's first look at the concepts covered in each unit.

1) Vector analysis:

Vector Algebra: Scalars and Vectors, Unit vector, Vector addition and subtraction, Position and distance vectors, Vector multiplication, Components of a vector.

Coordinate Systems: Rectangular, Cylindrical and Spherical coordinate systems.

Vector Calculus: Differential length, Area and Volume. Del operator, Gradient of a scalar, Divergence of a vector and Divergence theorem (definition only). Curl of a vector and Stoke’s theorem (definition only), Laplacian of a scalar.

Electrostatics:

Coulomb’s law and Electric field intensity (EFI)- EFI due to Continuous charge distributions (line and surface charge), Electric flux density, Gauss’s law (Maxwell’s first equation), Applications of Gauss’s law, Electric Potential, Work done in moving a point charge in an electrostatic field (second Maxwell’s equation for static electric field), Potential gradient, Laplace’s and Poison’s equations.

2)conductor - dielectrics and capacitance

Behavior of conductor in Electric field, Electric dipole and dipole moment- Potential and EFI due to an electric dipole, Torque on an Electric dipole placed in an electric field, Current density-conduction and convection current densities, Ohm’s law in point form, Behavior of conductors in an electric field, Polarization, dielectric constant and strength, Continuity equation and relaxation time, Boundary conditions between conductor to dielectric, dielectric to dielectric and conductor to free space, Capacitance of parallel plate, coaxial and spherical capacitors, Energy stored and density in a static electric field.
