Laplace And Poisson Equation, Lecture 5, 6, 7 And 8.
We will discuss 4 lecture hours of Laplace and Poisson Equation, their spherical coordinate forms and applications , boundary value problems in both spherical and Cartesian systems, there are 7 problems that are discussed in all details apart from required derivations.

Application of Gauss Law – Cylindrical and Planar Symmetry, Lecture-2
An infinitely long rod of negligible radius has a uniform (linear) charge density of λ. Calculate the electric field at a distance r from the wire. An infinitely long rod possesses cylindrical symmetry. Electric field E must be radially outwards from axis of symmetry of the rod, — for +ve charge. Consider a Gaussian surface…

Electric Field and Gauss Law, Lecture 1
Electric field is the amount of Coulomb’s force, that a positive charge of 1 unit experiences at a given position. Its a vector in the same direction as that of the electric force. We will discuss the time independent electric field which is also known as the static field. Advantage over electric force: Coulomb’s force…

Barrier potential and width in a pn step junction, L-VI.
Today we will discuss about the depletion region in greater detail than before. We will derive a quantitative relation among barrier potential and its width which are created in the depletion region, as discussed before. We will also derive an expression for the electric field that is established due to this potential. Lets first recall…

The Maxwell’s equations, from nature to instruments.
The beauty of Maxwell’s equations can be seen in how it helps us understand nature as well as instruments, at the same time. Medical devices are simply an advanced understanding that began with understanding electromagnetic waves through Maxwell’s equations. Each of the following 4 equations has a different name, by which we call’em, but together…
