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 is Transformer Testing : Types and Working
The transformer, as the name suggests is for transforming power from higher voltage to a lower voltage and vice-versa. In electrical engineering voltage for different functions/purposes is different; Therefore, the Transformer assumes a most important role. The importance of a transformer (distribution) is such, that it affects the general public directly as without electricity nothing moves. In order to perform, a transformer has to be tested thoroughly … [Read more...]
What is Star Delta Starter : Circuit Diagram and Its Working
The starting of an induction motor is associated with high inrush current (magnetizing and load). This inrush of current which maybe four to five times the full load current(FLC) of the motor poses problems in the supply system and the motor itself. In order to restrict the inrush of current suitable voltage reducing starting device is to be used. Star Delta starter being one such device. It may be added that with the improvement in the supply system and … [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 are Piezoelectric Material : Types and Their Properties
For the initial experimentations on piezoelectricity, the materials that were used were crystals and introduced the concept piezoelectric effect in the year 1880. With the investigations done on few materials, the two materials those exhibited maximum piezoelectric effect were Rochelle salt and Quartz. In continuity with the investigation done on a piezoelectric material, they exhibited good properties, characteristics, and benefits. And the initial … [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...]

These days, the scope of the entire technology revolves around electric devices, machines, and circuits. For all these, electricity stands as a fundamental component. 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 an Excitation : Types and Its Working
Excitation, the literal meaning is different in each stream of science and humanity. It is an increased activity of cells/organs in biological science in chemical science it is increased activity of various molecules and so on. In electrical engineering, the magnetic effect of current and its field which is known as excitation and only after an electrical machine gets excited it is ready to perform other functions like rotation/motoring or generation, etc. … [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...]
