The first moving coil galvanometer was invented in 1820 by Danish physicist Hans Christian Oersted as an improved version of the astatic galvanometer he had created a few years earlier. Since then, the design has been modified and improved to become smaller, more accurate, and more sensitive. The instrument is still widely used today in laboratories and factories all over the world for all types of electrical measurements. This article discusses an … [Read more...]
Step Down Transformer : Working & Its Applications
A Transformer is a static electrical device because it doesn’t have moving parts. The main function of a transformer is to change the electrical power from one electric circuit to another by changing voltage & current but not changing frequency. Transformers are classified into two types based on their function as a step-up transformer and step-down transformer. This article discusses an overview of a step-down transformer and its working with … [Read more...]
What is Tesla Turbine : Design & Its Efficiency
Initially, a steam turbine is a kind of device which is available in the form of a heat engine. This turbine receives most of its development in the thermodynamic efficiency by using various levels in the steam expansion that outcomes in a similar approach like reversible expansion procedure. This is the very basic principle of the turbine. The first device that was originated in the classifications of turbines is a steam turbine which is very compact like … [Read more...]
What is Tesla Coil : Working Principle & Its Applications
Before the invention of the Tesla coil, air-core transformers and electrical oscillations were introduced and the first invention of the tesla coil was done by Thomson Elihu in the year 1889, then after the patent rights for tesla coil was gained by Tesla in 1891. The first-tesla circuit came to known to the public as having the elements of the capacitor, high voltage transformer, spark gap, and oscillation transformer. At present, tesla coil devices … [Read more...]
What is Surge Arrester : Working, Types & Its Applications
With the evolution of the electric grid concept, engineers understood that new equipment is required for the protection of high-level voltage power devices. Devices like electrolytic arresters came into evolution during the period 20th century which is appropriate for high power requirements. Comparatively, the short-lived technology came into existence in the next 20 years. The contemporary word arrester was initially used in the period the mid-1800s … [Read more...]
What is a Form Factor : Peak Factor & Its Derivations
At the time when the supply of heaters and motors took place, the power stations provided a good sinusoidal signal voltage, and the load receives a sinusoidal wave current. The entire system is manufactured in the way to manage this signal where this seems to be ideal for efficient distribution. But there happened one issue which was that the transmission system brought in magnetizing current along with the load current. This led to the situation that … [Read more...]
What is Nodal Analysis : Features & Its Examples
We know that the electric domain is huge, and it all turns around electrical circuits and networks. So, analyzing an electric circuit is sometimes simple and in some cases, it turns to be too complex because we need to find out unknown voltages and current values at every node in the circuit. In order to make the circuit analysis process easy, there were mainly two approaches which are mesh and nodal analysis. Both techniques make the process of analyzing … [Read more...]
What is Mesh Analysis : Theory & Its Examples
In the analysis of various circuits, we all know that their analysis involves huge calculations and various equations, and other tools. Whereas in the case of complicated circuits, the analysis is not easy and using a simple analytical approach like series and parallel is not accurate. It needs multiple equations to solve and various techniques. So, the basic methodologies are improvised to Mesh Analysis that results in reducing the complexity of analyzing … [Read more...]
Different Types of Capacitors : Symbols & Their Applications
As we know that in the domain of electronics, capacitors are the most prominent devices which are extensively used in the design of various circuits. The key advantage of using a capacitor in electronic circuits is, its ability to store the electrical energy between its plates. These are the most considered components used for controlling the charge flow in the circuit. Capacitors along with devices like inductors and resistors come under the … [Read more...]
What is a Microbial Fuel Cell : Components & Its Applications
In the current world, we have been observing huge global energy catastrophes because of massive energy demands and the availability of only a few resources. This crisis happens because non-renewable resources are getting exhausted and renewable sources are not appropriately utilized. This creates a quick demand for searching alternate options for energy generation. And one of the options in microbial fuel cell technology. The thought of using microbes for … [Read more...]
