But it cannot be used to design or analyse a medium like free space 7. This is simplified approximation of field theory 8.

Circuit theory cannot be used to analyse or design a complete communication system Is useful at low frequencies At low frequencies the length of connecting wires is very much smaller than A. Cannot be applied in free space Is simple Basic laws are Ohms law, Kirchoff's laws Basic theorems are Thevenin's, Nortan's, Reciprocity, Superposition, Maximum power transfer theorems Ampere's circuit law Basic theorems are Reciprocity, Helmholtz, Stoke's, Divergence and Poynting theorems Basic equations are Maxwell, Poission, Laplace and Wave Copyrighted mai You have either reached a page that is unavailable for viewing or reached your viewing limit for this book.

Gauss was the first scientist who measured electric and magnetic quantities in absolute units. He formulated Faraday's law in He formulated the wave equations in Electromagnetics. He established Helmholtz theorem. He published the first Unified Theory of Electricity and Magnetism.

Founded the science of electromagnetism and formulated relations between electric and magnetic fields. These are the laws of Gauss, Faraday and Ampere. The Biot-Savart law was proposed in Heinrich Hertz Professor at the Karlsruhe Polytechnic.

In he assembled the apparatus for a complete radio system with an end-loaded dipole as transmitting antenna and a resonant square loop antenna as receiver.

A Neper is defined as the natural logarithm of the square root of the power ratio, that is, INp. Properties of Complex Numbers 1. Two complex numbers are equal if their real parts are equal and their imaginary parts are also equal.

The Cofactor The cotactor of an element in a determinant is its minor with a suitable sign. The matrix obtained from a given matrix A by interchanging rows and columns is called Transpose of A denoted by K. A' Adjoint of a matrix A is the transposed matrix of cofactors of A. Both the matrix and its inverse must be non-singular.

Inverse of a matrix is unique. A matrix is said to be of rank r when it has at least one non-zero minor of order r and every minor of order higher than r vanishes. It means that the rank of a matrix is the largest order of any non-vanishing minor of the matrix.

Yes 8. Yes 9. No Yes Radius of cylinder Radius of sphere These fields are not variant with time. They are produced by static charges or charge distributions. These fields have a wide range of applications. In this chapter, the important laws, theorems and equations, with their applications are presented to provide a thorough understanding of electrostatics.

The important areas are Coulomb's and Gauss's laws, Stake's and divergence theorems and Poisson's and Laplace's equations.

Find D and E at 3, 4. Find the electric field at P l, 0, 1. Also find the electric flux density at P. The normal component of D is continuous across any boundary except at the surface of the conductor.

A conductor consists of a large number of free electrons which constitute conduction current with the application of an electric field.

The Electromagnetic Field Strength Tensor

A conductor is an equipotential body. The potential is same everywhere in the conductor. In a perfect conductor, conductivity is infinity.

When an external held is applied to a conductor, the positive charges move in the direction E and the negative charges move in the opposite direction. This happens very quickly. Free charges are confined to the surface of the conductor and hence surface charge density, J s is induced. These charges create internal induced electric field.

This field cancels the external field. It is interesting to note that copper and silver are not super conductors but aluminium is a superconductor for temperature below 1. It is a scalar, that is, j s — — , Ampere dt Current is of three types.

Convection current 2. Conduction current 3. Displacement current 1.

Convection current It is defined as the current produced by a beam of electrons flowing through an insulating medium.
