The history of electrical conductance invention takes back to the eighteen and nineteen centuries where Mr. Benjamin Franklin (1706–1790) observed that electrons could travel along the path of the metallic rod; which also resulted in the invention of a lightning rod. Mr. Alessandro Volta (1745-1827) studies on static electricity have led to the discovery of electric potential and the principle behind the development of batteries. Mr. Georg Simon Ohm … [Read more...]
What is Piezoelectric Transducer : Theory, Circuit, Formula & Applications
We all might come across the situations of energy conversions either in our day-to-day life scenarios or in industrial purposes. So, for the conversion of energy, we need a device to calculate the unfamiliar quantities and calibrations. And the device that comes into invention is “Transducer”. As every scenario that we come across either directly or indirectly related to the energy conversion, there are many kinds of transducers and their application is … [Read more...]
What is Dielectric Heating : Circuit Diagram and Its Working
We all know that the progression of technology enhances day-by-day through the invention of various trends and creativities. In the same way, the approaches to cooking food and making use of fire also get enhanced. We are completely aware of how to cook, molding of metals and procedures followed in various industries and many others. But the greatest revolution that came into existence was to work on the same thing without the utilization of fire. The … [Read more...]
Types of Transformers and Their Working
The development of the electrical and electronics industry seems to be continually progressing with the invention of various electronic devices. The one device that has to be probably discussed is a Transformer. There is a wide range of applications through a transformer and just not with a single type of transformer, scientists have invented various kinds and each one has its own applications and advantages, either in commercial or real-life scenarios. … [Read more...]
What is Earthing : Components and Its Types
We know that all the electrical and electronic appliances run on electricity. The home appliances are like air conditioners, refrigerators, televisions, greasers, washing machines, grinders, etc. Have you ever noticed that why the plug systems on the wall contain three pins instead of two pins? Home appliances are designed with metals, metal components, and metal frames. Metals are great conductors that allow the flow of current through it. But there is a … [Read more...]
Induction Heating Working & Its Applications
The fundamental induction heating principle was introduced and applied in manufacturing industries in 1920. During the Second World War, the development of technology has been increased to reach urgent requirements of a period of war for a quick, consistent procedure to solidify the parts of the metal engines. At present, technology is focusing on lean industrialized methods & giving importance to improved quality control of induction technology. This … [Read more...]
Maximum Power Transfer Theorem – Examples and Applications
In any electrical system, the highest amount of power is used to transmit the power to the load for its operation. the best example of this is an audio amplifier as they transmit the maximum amount of current from the amplifier to the speaker. Similarly, in radio system, the highest amount of current is supplied from the power amplifier to the antenna. For this, the value of load resistance should be ideal for supplying the highest amount of current toward … [Read more...]
Overvoltage and Under Voltage Protection System
If any unexpected fluctuation in the power supply may cause many problems in the industries, homes, offices. Voltage fluctuations in the electric power supply have a very poor effect on connected load. These fluctuations of over voltage and under voltage protection system are produced by many reasons which are like voltage surges, limiting, overload and etc. General applications of these systems are used in agriculture motors, water pumps and etc. In this … [Read more...]
Basics of 555 Timer IC and Working Principle
In the year 1971 by Hans R. Camenzind has designed the 555 timer integrated circuit with the contract of Signetics. Later on it came to Dutch company which is Philips semiconductors. The manufacturing of 555 timer IC includes the transistors, diodes, and resistors on the silicon chip which are on the 8 – pin mini dual in line packages. There are different types of timers available like 556 which include the 14 pin dual in line package are gathering the … [Read more...]
Steps to Convert AC to DC – Converter & Circuit
Electrical power supply became as a basic need in our day-to-day life, the power we are availing is 230V 50Hz AC supply. But, by using power electronics converter circuits this power can be converted into the required form and range. These converters are power electronics circuits which are further classified as step-down & step-up converters, voltage stabilizer circuit, AC to DC, DC to DC, DC to AC converter circuits and so on. Most of the … [Read more...]
