The distribution of current throughout cross section of a conductor is uniform only when DC is passing through it. When Alternating Current(AC) is passing through a conductor, the current is non uniformly distributed over the cross section in a manner that the current density is higher at the surface of the conductor compared to the… Read More »
Being an electrical engineer on a construction project is a very tedious and responsible job. Electrical site engineer is wholly responsible for the ordering of materials as per the pre approved material submittals and an electrical project specifications. Here in this article we have included the complete list of testing requirements for an electrical system… Read More »
Spontaneous magnetization is the appearance of an ordered spin state (magnetization) at zero applied magnetic field in a ferromagnetic or ferrimagnetic material below acritical point called the Curie temperature or TC. Heated to temperatures above TC, ferromagnetic materials become paramagnetic and their magnetic behavior is dominated by spin waves or magnons, which are bosoncollective excitations… Read More »
Distributions systems represent an important parts in the electrical grids and for this reasons the electrical generation & distribution companies delicate approximately 40% of the capital investment for distribution systems while the remaining is given to generation and transmission (40% generation & 20% transmission). The power distribution system is particularly important for an electrical utility… Read More »
Very basic question which an electrical student or professional may be asked is what is electric current and electric charge. The electric current is actually the flow of electric charge from one point to other point of the conductor or wire or cable. In electric circuits this charge is often carried by moving electrons in a… Read More »
In a paramagnetic material the magnetization of the material is (approximately) directly proportional to an applied magnetic field. However, if the material is heated, this proportionality is reduced; for a fixed value of the field, the magnetization is (approximately) inversely proportional to temperature. This fact is encapsulated by Curie’s law: where is the resulting magnetisation… Read More »
