In digital electronics, basic logic gates are the important components of all digital devices and systems. A logic gate is a digital circuit whose operation is based on the Boolean function. Thus, logic gates are used for performing different logical operations on binary inputs to produce a binary output. Therefore, ... Read More

The electron theory of matter is one of the most successful and experimentally proved theory that can explain the nature of electricity. Although the study of electricity has been attracting the attention of scientists for several hundred years, and there were several experiments and theories developed to understand the nature ...

Engineering materials can be classified into two broad categories namely metals and nonmetals. This classification of engineering materials is based on their physical and chemical properties. In this article, we shall discuss the differences between metals and non-metal, but before we will learn that what metals and non-metals are. What ... Read More

In electrical and electronic circuits, the power is one of the most significant quantities used to analyze the circuits for practical applications. The electrical power defined as the time rate of expanding or absorbing energy in a circuit, i.e., $$\mathrm{Power, P=\frac{Energy \;expanded\; or\; absorbed (𝑊)}{Time(𝑡)}}.....(1)$$ This article is meant for ...

Grounding, also called earthing, is defined as a process of connecting non-current carrying parts like metallic frame of electrical device or some electrical parts of power system like neutral point of a star-connected system to earth or ground. The main purpose of doing grounding in electrical systems is to prevent ... Read More

What is Voltage? Voltage, also called potential difference, electric pressure or electric tension, is defined as the difference of electric potentials of two points in an electric circuit. In other words, the amount of energy required to move an electric charge from one point to another in an electric circuit ... Read More

In this article, we shall learn about Permeance in magnetic circuits, its definition, formula, unit of measurement, and coefficient. What is Permeance? The measure of the ease with which the magnetic flux can flow through a magnetic material is called Permeance. It is denoted by the symbol P and given ... Read More

Energy is required to perform many functions in day-to-day life. Energy exists in different forms in nature, but the most important form of energy is electrical energy (or electricity). As we can experience, electricity has become an integral part of our life because without electricity we cannot imagine our life. ... Read More

What is SWR Meter? SWR meter stands for Standing Wave Ratio meter, it is a measuring instrument used to measure the standing wave ratio (SWR) in a transmission line or transmitter feeder. It is also known as VSWR or ISWR. There are different types of SWR meters available, however, the ... Read More

In electrical and electronics engineering, we must deal with measurable quantities. Therefore, as electrical engineers, we have to communicate in a standard language that all professionals can understand, irrespective of the country in which the measurement is performed. Such a standard language of measurement is the International System of Units ... Read More
