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 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...]
What is an Electric ARC Welding : Principle, Types & Applications
The concept of welding starts from the ancient time itself where the fundamental process is to join two metal pieces. With the development of technology, there was an enhancement in the welding technologies also. In the initial days of the 19th century, there happened a great revolution in the domain of welding and it was using heat resources for the welding process. Especially, welding technologies gained prominence at the time of welding requirements in … [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...]
