The theory in the electrochemical procedure, metals such as aluminum, niobium, cadmium, and others create an oxide coating that obstructs the actual flow of current directions but allows to flow in the opposite paths. This phenomenon was initially observed by Johann Buff in the year 1875 and its implementation was done by Ducretet. The manufacturer of accumulators namely "Charles" came to know that the oxide coating stays stable in the case of alkaline and … [Read more...]
What is Surface Condenser : Working, Efficiency & Its Applications

This requires arranged maintenance and assessments to stay away from any kind of breakdown at the time of sailing. So, for onboarding purposes, there exist various devices and to measure multiple electrical factors. One of the instruments is the PMMC instrument (Permanent Magnet … [Read more...]
What is a Stepper Motor Driver : Types & Its Working
Motors are the most crucial development, and they play a wide role in many of the domains like engineering, electrical, and others. As the prominence of controlling motors is enhancing, there come wide variations in motor development such as variation in its speed level, type, and sizes. And the one type of development is stepper motor driver which is a kind o controlling the motor. The development of stepper motors took place during the period when the … [Read more...]
What is a Superconductor : Types & Its Applications
The theory of superconductivity came into existence in the year 1911 when the temperature of mercury was nearly 40C by the physicist Onnes for which he won the Nobel prize. From then, the concept of superconductivity progressed, and various kinds of superconductors were discovered. Later on, with many inventions, superconductors also tend to function even at higher temperature levels. The invention of high-temperature kind of superconductors reached … [Read more...]
What is a Photocell : Types, Working & Its Applications
In the year 1883, the inventor from America namely Charles Fritts developed a functional photoelectric cell. In the same year, Paul an engineer from Germany utilized the photocell in his observation called Nipkow’s disk. This is the instrument that takes images by measuring the object’s bright and dark locations and convert those into impulses in electrical form. The pre-invention of the modern-day photocell was developed by Hans and Elster by giving … [Read more...]
Different Types of Losses in Transformer & Their Impact
The transformer is the most prominent passive device that has the operation of transferring electrical energy from one circuit to another, it is used in various applications across multiple domains. Also, there are a wide variety of transformer designs in electrical and electronic domains, every type encounters various types of losses in transformer. So, it is even more crucial to know the types of losses in the transformer and how these losses show an … [Read more...]
What is Damping Ratio : Formula & Its Derivation
It has been observed from the past twenty years that there happened many earthquakes all over the world which resulted in several fatalities and damages. These losses were because of the seismic excitation and resulted in both non-structural and structural catastrophes. So, it is important to enhance the seismic performance of the constructional structures. This can be done by implementing passive energy-dissipation and this provides improvised solutions … [Read more...]
