Specific resistance is the measure of the conductivity of a particular element and it is also known as electrical resistivity. Based on the value, the conductivity, and hence the electrical characteristics of the element are evaluated. This parameter is often used to analyze the electrical conductivity of a particular element, and hence have prime importance while selecting the elements. Some applications need elements that have superior electrical … [Read more...]

What is Plasma Arc Welding : Working and Its Types
In the bronze age itself, the concept of welding was in implementation. An example of this is the making of gold boxes with the assistance of pressure welding. At the time of middle ages, the concept of blacksmithing was formed to weld iron pieces. Every consecutive year, there comes the evolution of a new type of welding and plasma arc welding is the one. This process was discovered by Robert M.Gage in the year 1953. The unique feature that made this … [Read more...]
What is Three Phase Transformer : Circuit Diagram and Its Working
In this industrial era, the transformer stood as a crucial invention as it serves the requirements and necessities of multiple industries. The essence of the transformer lies completely in its energy conversion. Based on the principle of electromagnetic induction, Faraday expanded this concept to a transformer and even this device almost functions on the same principle. So, the primary kind of transformer that was invented in the induction coil. Whereas, … [Read more...]
What are Electric Field Lines and Its Properties
Electric field lines may be considered as a visual representation of the electric field existing between or for a charge itself. It was introduced by Michael Faraday in the year (1791-1867) who named them lines of force. A field basically is a function that specifies a particular quantity everywhere in a region. When we say electric field lines, it gives us means of representing the electric field pictorially. By looking into the electric field lines, its … [Read more...]
What is a Piezoelectric Effect : Materials and Its Applications
We may use many materials like cane sugar, quartz, Rochelle salt, and others without knowing what exactly they are and their benefits. But today, this article explains you clearly on these materials because these are piezoelectric materials and they are evolved with piezoelectric effect. This effect was first observed by Jacques Curie and Pierre in the year 1880. With the knowledge they have on the concept of pyroelectricity and crystal structures and … [Read more...]
What is Zener Diode : Circuit, Working Principle & Characteristics
In the developmental era of semiconductor diodes itself, Zener diodes were founded. Every electronic circuit is basically composed of diodes. So, diodes hold utmost prominence in the development of electrical and electronic devices. The characteristics of Zener diode were initially described by Clarence Melvin Zener in the year 1934. From then, there has been enormous progress in the implementation of these devices. To know about Zener diodes, one has to … [Read more...]

The enhancement and the progression of multiple phases in electricity increased the development of many electric devices. Of many devices, the one which grabs the attention of many customers to implement in their industries is “Rheostat”. Being in optimization with the recent trends and … [Read more...]
What is a Bridge Rectifier : Circuit Diagram, Types & Its Working
As we all know how crucial electronic circuits are in use these days. We can say that the entire scope of software, industrial, engineering, medical and agricultural industries are either in the way connected to these electrical circuits. So, moving in this scenario, rectifiers are the circuits that appeared as the most common electronic power supplies. As many circuits need DC power source to power up many electric components. So, the device which holds … [Read more...]
What is a Centre Tapped Full Wave Rectifier : Working & Its Equations
From the period 1880’s, the concept of rectifiers has established an identity and they proved themselves to be so prominent in the electronics industry. Whereas the evolution of vacuum diodes has confined the development of rectifiers. Vacuum diodes allow for current movement only in a single direction, but with the implementations such as mercury tubes, rectifiers permitted for the flow of multi-megawatt power ranges. So, the enhancement of vacuum diodes … [Read more...]
What are Electrical Conductors : Types and Their Properties
In the period of the 18th and 19th centuries, the concept of electrical conduction took place. And in the scope of electrical and physical engineering, conductors are most necessary to generate the current flow. The concepts of conductors, insulators and electric field came up with the thoughts and experiments done by many scientists and the person who stood behind the invention of these was Stephen Gray in the year 1734. From then the theories such as … [Read more...]
