As the prominence of audio, video and other broadcasting technologies are enhancing day-by-day. There have to be certain amplification ranges to increase the quality and effectivity of the broadcasting signals. In the scope of this, the first amplification device that came into existence was a triode vacuum tube in the year 1906. There come many devices used for this cause and those are transistors, multistage amplifiers, and RC coupled amplifiers. As … [Read more...]
What is Temperature Coefficient of Resistance
As we are in the era of digital technology, the foremost concept to be known about is electronic engineering. As every industry in this digital scope needs of electronic instruments, one has to be clearly aware of its concepts and properties. The one concept which we are going to discuss is the temperature coefficient of resistance. When there is current movement through the wire, heat gets generated through this because of resistance in the wire. This … [Read more...]
What is Monoblock Pump : Working and Types
Well, we all know that pumps are the instruments to create a movement in the fluids through some sort of mechanical activity. And depending on the mechanical action, pumps have many classifications like velocity, gravity, steam, and valveless pumps. So, today we are going to have our discussion on one of the specific kinds of the pump and it is “Monoblock Pump”. This kind of pump also holds various benefits to be implemented in irrigation, construction … [Read more...]
What is Submerged Arc Welding : Working and Its Applications
Welding is the concept of joining two metals through some external procedures and the concept which stood as basic for welding is lap welding. Then after, this domain observed huge progression with the usage of metals such as bronze and copper. To the clear, this progression was driven by human enhancements in the invention of multiple instruments. In the 20the century, there comes the scene of electricity and this prompted the discovery of various … [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 Distribution Transformer : Construction, Types & Its Uses
The men behind the invention of the transformer are William Stanley, Lucien Gaulard and Sebastian and employed the device for both commercial and practical applications. Then, the modern type of transformer was invented in the year 1886 where this used AC power as the power source. Ranging from radio systems to microelectronics, these transformers are extensively utilized from the time of their invention. The presentation of the distribution transformer … [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 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...]
