A device that is used for indicating and measuring various electrical quantities like current, voltage, energy, power, etc. is called a measuring instrument. Based on the functionality, the instruments can be classified in several types like indicating instruments, integrating instruments, recording instruments, etc.In this article, we will highlight all the differences between indicating instruments and recording instruments. Let's start with a basic overview of these two types of instruments. What is an Indicating Instrument? The measuring instruments which indicate the magnitude of the electrical quantity at the time when the quantity is being measured are known as indicating instruments. A ... Read More
Electrical power is produced at the generating plants, from where it is transmitted over the long distances for utilization at the load points. Since, the transmission of electrical power is performed with the help of transmission conductor. Hence, due to the line parameter, some power loss occurs during the transmission. Hence, in order to reduce the power loss during the transmission, we need to take some necessary actions. One major of them is to increase the transmission voltage to higher values. The line voltage plays an important role in reducing the losses in transmission line. The increase in the line ... Read More
A WAN in general is a network of local area networks (LANs) that link to other LANs via telephone lines and radio waves. WAN connections can include both wired and wireless technologies. Wired WAN services include carrier Ethernet, commercial broadband Internet links, etc., whereas wireless WAN technologies include cellular data networks like 4G LTE, public Wi-Fi, satellite networks.LANs are privately owned and span a smaller geographical area (restricted to a few kilometers). It can be used in various settings, including offices, residences, hospitals, and schools. The setup and management of a LAN is quite straightforward.Go through this article to find ... Read More
A cell is a device that converts chemical energy into electrical energy and vice-versa. The behavior of the cells is studied in a branch of chemistry called electrochemistry, where we learn about the relation between the movement of electrons in a system and the chemical processes take place in the system. These chemical processes can produce electricity. The system in which chemical energy is converted into electricity and vice-versa is called a cell. The cells are classified into two major types namely − Electrochemical cell Electrolytic cell In this article, we will highlight how electrolytic cells are different ... Read More
It is a well-known fact that the electric current is the flow of charges. This charge may be carried by electrons or ions. Hence based on the charge carriers and physical state, there are two types of substances used for current conduction namely electrolytes and conductors. Both electrolytes and conductors are used to carry the electric current, however there are several differences between them. This article will help you understand the major differences between an electrolyte and a conductor. What is an Electrolyte? An electrolyte is a substance whose aqueous solutions are the conductors of electricity. In simple words, a ... Read More
A circuit breaker is an electrical switch that is designed to operated manually as well as automatically either in normal conditions or in case of a fault in the system. Therefore, a circuit breaker can also function as a protective device which can protect the system equipment and the operators. There are several circuit breakers are designed for this purpose, two of them are ELCB and RCCB. In this article, you will learn what ELCB and RCCB are, and what are the major differences between them. What is an ELCB? ELCB stands for Earth Leakage Circuit Breaker. The ELCB ... Read More
The process of turning plain text into an encrypted form (cipher text) is known as encryption. Sensitive data is transmitted in an encrypted form so that it can be protected and a strong encryption mechanism ensures that the data is not misused even if a hacker gets hold of it. Decryption is the reverse mechanism where the encrypted cipher text is converted back into its original form.Read through this article to find out more about encryption and decryption and how they are different from each other.What is Encryption?Encryption is the procedure of encoding data in cryptography. This procedure turns plaintext, ... Read More
Connection-oriented and Connection-less Services are used to establish connections between two or more devices. Connection-oriented Services A connection-oriented service is one that establishes a dedicated connection between the communicating entities before data communication commences. It is modeled after the telephone system. To use a connection-oriented service, the user first establishes a connection, uses it and then releases it. In connection-oriented services, the data streams/packets are delivered to the receiver in the same order in which they have been sent by the sender. Connection-oriented services may be done in either of the following ways − Circuit-switched connection: In circuit ... Read More
Roman numerals are a type of number system used to represent a fixed decimal number. Several letters from the Latin alphabet are used for the representation of roman numerals. In this tutorial, the user will learn how to convert a decimal number to roman using JavaScript. Seven symbols represent Roman numerals: I, V, X, L, C, D, and M. The values for symbols are given below. Syntax I is 1 V is 5 X is 10 L is 50 C is 100 D is 500 M is 1000 Using these seven symbols user can convert decimal numbers to roman. ... Read More
In this tutorial, we will learn how and why ‘z’[‘toUpperCase’]() works in JavaScript. From the given format, we can say that it calls the toUpperCase() method for the ‘z’ string. It will work the same as the toUpperCase() method, which we invoke by taking any string as a reference. Let’s understand the syntax of the ‘z’[‘toUpperCase’]() below. Syntax let result = 'z'['toUpperCase'](); // returns 'Z', string in upper case The above syntax is same as the below. Example let string = 'z'; let result = string.toUpperCase(); Why does ‘z’[‘toUpperCase’]() work? In JavaScript toUpperCase() method is used to convert ... Read More
