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...]
What is a Rheostat : Construction and Its Working
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 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...]
What is Pump Cavitation : Causes and Its Solutions
Initially, the speculation of cavitation was known in the period 1754 by Euler and later on the solution to this was presented by Henry Besant in 1859. Thornycroft and Barnaby were the persons who observed the scenario of cavitation on the behind sides of propeller blades. In the context of engineering, pump cavitation is the concept that has to be considered in a high priority, because when it left unobserved, there are chances of the machine getting … [Read more...]
What is an Electric Field Intensity and Its Calculation
Intensity basically defines the strength of the source like light intensity, which defines the luminosity of light source, electromagnetic field intensity defines the strength of the magnetic field. Similarly, electric field intensity defines the strength of the electric field. This is a vector quantity, which basically means force per unit charge. This parameter is extensively used in the field of electromagnetics, electrostatics, high voltage … [Read more...]
What is a Screw Pump : Working Principle, Types and Benefits
When compared to centrifugal pumps, positive displacement pumps are the most effective ones and screw pumps come under this classification. It came to know that conventional kinds of screw pumps were in availability in the ancient period itself. Then after the screw pump was pioneered by Archimedes. The pumps that were invented initially consists of a cylinder, a revolving unit, and a spiral tube. With the advancements in technology, the operating … [Read more...]
What is a Gear Pump : Design, Working Principle and Types
Pumping industry became extensively prominent from 1982 itself and there onwards there have been multiple enhancements and inventions. One of the developments which stood as the great invention is positive displacement pumps and their types. Enhanced environmental knowledge gave a real development to pumps having no shaft seals. The trend of electronics and computers even entered into the scope of pumps in the aspect of variable speed drives. Pump choosing … [Read more...]
