Introduction to Electricity Distribution Electricity distribution refers to the process of distributing the electrical power from generating stations to the consumers. In the first step, electricity is distributed to substations from the generating stations through transmission lines by increasing the voltage level to reduce transmission losses. In the second step, the increased level of voltage is stepped down using the transformers and supplied to consumers by the utility companies. In any industry, more than one voltage level is used for different purposes like 415 V, 690 V, 6.6 kV, and 11 kV. There is a process of voltage conversion ... Read More
In electrical power system, electrical earthing is one of the most important concept used to provide safety and protection to both human and equipment. Electrical earthing, also called as grounding, is basically a path of very low-resistance between the electrical equipment/system and the earth surface. The main purpose of electrical earthing in an electrical system is to provide a safe path for leakage electric current to flow into the earth’s conductive surface to reduce the risk of electrical accidents. Therefore, electrical earthing is an efficient and reliable way of protecting electrical equipment, individuals, and premises against electrical faults ... Read More
Optical fiber technology is defined as technology that is capable to transmit information in the form of light pulses with the help of a high-quality glass or plastic material. It looks like a transparent filament. In this article, we will go through optical fiber, its types, and the differences between them. So, let's begin with the definition of optical fiber. What is an Optical Fiber? Optical fiber is thin a thin or flexible glass or plastic material used to transmit information in the form of light. Glass or plastic serves as a medium to allow the passage of ... Read More
Finding the tag and the HTML tree's content indicates searching the parse tree using BeautifulSoup. There are other ways to accomplish this, but the find() and find_all() methods are the most popular for searching the parse tree. We can use BeautifulSoup to parse the HTML tree with the help of these techniques. One benefit of applying Beautiful Soup is that even when we are moving from another language, it is simple for beginners to learn. It provides excellent, thorough documentation that makes it easier for us to pick things up quickly. Syntax The following syntax is used in the examples ... Read More
The automotive industry is undergoing a major revolution in the method we power our vehicle. The hybrid electric vehicle (HEV) and electric vehicle (EV) are at the leading position of this revolution. The fundamental difference between hybrid electric vehicle and electric vehicle is that electric vehicle relies only on electric batteries as energy source, while hybrid electric vehicle uses both fuel and electricity as the energy source. In this article, we will explore the other major differences between hybrid electric vehicle and electric vehicle. But before that let’s briefly get their overview individually. What is a ...

The dataframe in PySpark is defined by a shared collection of data that can be used to run in computer machines and structurize the data into rows and columns format. The range of rows defines a horizontal line(set of multiple values according to condition) in the dataset. In general, the range sets the lowest and highest values. In Python, we have some built-in functions like filter(), where(), and, collect() to select a range of rows from a dataframe in PySpark. Syntax The following syntax is used in the examples − createDataFrame() This is a built-in method in Python ... Read More
In digital electronics, a D/A converter, also called Digital-to-Analog Converter, is an electronic device that converts digital signal inputs into analog signal outputs. Depending on the polarity of output signals, D/A converters can be classified into two types namely, Unipolar-Output D/A Converters and Bipolar-Output D/A Converters. A unipolar-output D/A converter can produce only positive analog signals as output, whereas a bipolar-output D/A converter can produce both positive and negative analog signals as output. In this tutorial, we will discuss bipolar-output D/A converts, along with their construction, types, working, advantages, and applications. So, let’s start with the basic definition ... Read More
Seaborn is a Python data visualization library based on Matplotlib. It provides beautiful default styles and color palettes to make statistical plots more attractive. It is also closely integrated with the data structures from Pandas. Seaborn aims to make visualization the central part of exploring and understanding data. This type of charts allows users to switch between different visual representations for the same variables for a better understanding of the dataset. Seaborn is used in various applications for visualizing the relationship between variables, examining univariate and bivariate distributions, and more. A univariate distribution shows the distribution of a single variable, ... Read More
In digital electronics, block coding is a technique of encoding data into a specific format. It is mainly used to detect and correct errors occurred in the information during transmission and storage. This is done by adding a block code of redundant information to the main data. Block coding is mainly employed to create a robust method of data transmission and storage. In the block coding, data is encoded by splitting it into multiple blocks of a fixed size and applying encoding techniques to each of these blocks separately. In block coding, the input data is taken ... Read More
The 3D Tensor in Python is known for its array of matrices whereas the 1D and 2D Tensor represents vector and matrix respectively. The Pytorch is defined by an open-source module of machine learning framework based on Python programming and it provides the module named torch. In Python, we have some built-in functions like randn(), rand(), and split() that can be used to represent the slice of a 3D tensor in Pytorch. Syntax The following syntax is used in the examples − import torch This is a Python module that holds the base class of all neural networks. It ... Read More
