Updated on 15-Nov-2022 07:33:28
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 path for current to flow. Technically, an electric circuit element is the mathematical model of an electrical device and can be completely characterized by its voltage and current relationship. Also, a circuit element being the most basic building block cannot be subdivided into other devices. There are three most basic ... 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 divided into sub-components. The common examples of circuit elements are resistors, inductors, capacitors, energy sources, etc. Types of Circuit Elements Depending on the behavior in the circuit, the electric circuit elements can be classified into the following types − Active Elements Passive Elements Unilateral Elements Bilateral Elements Linear Elements ...

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 numbers. There are several types of number systems and the basis of this classification is the base or radix of the number system. The base or radix of the number system is the total number of symbols used to denoted the numbers in the number system. Types of Number Systems ... Read More

What is Electrical Impedance?

Manish Kumar Saini
Updated on 15-Nov-2022 13:16:22
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 complex quantity, i.e. it has both magnitude and phase. The electrical impedance is basically the extended concept of resistance. It is the function of frequency of alternating current flowing in the circuit. It because the impedance comes into picture only when there is a frequency dependent element like inductor or ... Read More

Updated on 02-Nov-2022 06:51:26
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 is called voltage. Voltage is denoted by the symbol V or v, where V is used to represent a constant voltage, while v is used to represent a time-varying voltage. In this article, we will learn all about voltage, and the methods used for measuring the voltage in an electric ... Read More
