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...]
What is Resistance Welding : Types and Their Principles
In the prehistoric period, the scope of welding was forge welding where this process follows up with metal heating and then brazing. But, the enhancements and innovations of technology have shown development in the era of welding that by the end of the 19th century, people became more modernized and their welding techniques also adapted to the change. Arc welding, resistance and gas welding are the fundamental welding techniques employed in many … [Read more...]
What is a Current Transformer : Working Principle and Its Advantages
The current transformer (CT), also known as an instrumental transformer, is used to either reduce or propel the primary current across the secondary winding. The current produced across the secondary terminal is directly proportional to the primary winding. In high power circuits, the voltage across the primary side is scaled down to a minimum value, which helps to measure the actual AC transmission current through standard ammeter safely. In this article, … [Read more...]
What is a Diaphragm Pump : Working Principle & Its Applications
Pumps have a long period of history and they were into existence from 2000 B.C. To fetch water, the initial tool that was invented was called shadoof. Even it does not function in the mechanical approach, it was widely accepted by many and best serves the pumping activity. The construction of all these stood as the basis for the development of diaphragm pumps and they were into the market from 1854 onwards. The basic invention of the diaphragm pump was … [Read more...]
