Electrical impedance is the measure of opposition produced by circuit elements in the path of alternating current. Therefore, the electrical impedance is the parameter related to the AC circuit. The electrical impedance is usually denoted by the symbol ‘Z’ and is measured in ohms $\mathrm{(\Omega)}$. The electrical impedance is a ... Read More

A system that is used for representing numbers is called the number system. In digital electronics, the numbers are used to represent the information. Hence, it is important to learn and understand different types of number systems so we can easily represent and interpret the information in the form of ... Read More

There were several theories stated to explain the arrangement of subatomic particles. The Plum Pudding Model, also known as Thomson’s Plum Pudding Model, is also a scientific model for explaining the arrangement of subatomic particles. This model was first proposed by a British physicist Sir J. J. Thomson in 1904. ... Read More

In electrical and electronics engineering, we frequently come across two terms "circuit" and "circuit element". Where, an electric circuit element is the most elementary building block of an electric circuit, and the electric circuit is an interconnection of different circuit elements connected in a fashion so they form a closed ...

In electrical and electronic circuits, there are five major electrical quantities that used to analyze circuits. These quantities are electric charge, electric current, voltage, electric power and electrical energy. In this article, we shall learn about these quantities in detail. What is Electric Charge? Electric charge or simply charge is ... Read More

A circuit element is the basic building block of an electric circuit. Basically, a circuit element is a mathematical model of an electrical device which is characterized by the relationship between voltage and current. The circuit element is the most elementary part of a circuit, therefore it cannot be further ... Read More

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 ...
