What are Outliers? Outliers are the data points or observations which are far from the other points in a dataset. Outliers are caused due to measurement error, data entry error or experimental error etc. Outliers can skew the dataset which effects in statistical analysis and can increase the standard deviation of the dataset further effecting model prediction. An outlier may be a valid data point or can be noise. For a better understanding let us look at an example scenario. Imagine you are collecting data of student's height (age between 9 to 12 years). Most of the students are around ... Read More
What is a Higher Order Function in JavaScript? JavaScript being a multi paradigm language, it supports procedural programming, functional programming and object oriented programming. Since it is also a functional programming language javascript handles functions as a first class entities, where functions can be assigned to a variable, set it as an object's property, and can pass them as an argument to another function. This characteristic in javascript helps in implementing Higher Order Functions, which can operate on other functions either by taking them as an argument or by returning them. Let us take an example and implement it ... Read More
Introduction Data handling and data representation are the processes of collecting and presentation of data systematically. Data handling is the act of collecting a set of data and presenting it in various formats data handling. The act of collecting, maintaining, and presenting data in a way that facilitates analysis, forecasting, and decision-making is known as data handling. Here in this tutorial, we shall discuss in brief data handling, central tendencies, frequency tables, how to represent data in graphs, and examples related to data handling. What is Data Handling? The initial collection of observations is referred to as the raw data. ... Read More
Monocrystalline solar panels are one of the most popular types of solar panel available in the market and is used for generating electricity from sunlight. The primary reason behind its popularity is its relatively high efficiency in all weather conditions. Although it is a relatively expensive solar panel than other types of solar panels. In this article, I will explain all the important concepts of the monocrystalline solar panel, such as its construction, advantages, disadvantages, and applications. So, let’s start with the basic introduction of the monocrystalline solar cell which is its fundamental building block. What is a ... Read More
The increasing demand of electricity cannot be met through conventional ways of generating electricity. To fulfil the electricity demand, several new methods have been developed. Solar panels are one of the most common of them. A solar panel is a semiconductor device that can convert sunlight into electricity. This light to electricity conversion is based on the principle of photovoltaic effect. Thus, solar panels are also known as photovoltaic systems. In a solar panel, there are multiple PV or solar cells used that absorb the sunlight and produce electricity. This electricity is stored in rechargeable batteries and supplied as per ... Read More
Solar energy is becoming one of the most popular methods of generating electricity. It is because the solar energy is clean and does not cause any environment pollution like green-house effect, air pollution, etc. Also, it is renewable, as it will deplete over time. The solar energy is freely available from the sun light and we can develop certain kind of mechanisms like solar panels to utilize the solar energy. A solar panel is an opto-electric device that is used for converting energy from sun light into electricity. Based on the technology used in manufacturing the solar panels, there are ... Read More
In the field of electrical and power distribution engineering, there are two important concepts namely neutral and floating neutral. The neutral, also called neutral wire, is a return path for electric current in electrical circuits that balances the phase loads and serves as a reference point. In practical applications, the neutral is typically grounded at the main panel or distribution end. On the other hand, the floating neutral is also a neutral wire but it is isolated from the ground terminal. The concept of floating neutral is not much common in practical applications, but it may be used in ... Read More
Introduction One billion can be written as 1 , 000 , 000 , 000 . In mathematics, place value can be used to define numbers. There are two different ways to represent the place value of the digits in the numbers. The positional values of the number are determined using place value charts. Positions allow for the expansion of the numbers in the general form. In this tutorial, we will learn about billions in rupees, the number system, and the conversion of the number system. Number Systems Number systems are mathematical expressions of numbers in various ways that computers ... Read More
This article is meant for explaining the two most widely used visual representations of electrical systems also called electrical diagrams. These diagrams are single-line diagram and multiline diagram. These two diagrams are used in electrical engineering to represent various electrical layouts and connection arrangements of electrical systems. In electrical engineering, the visual/graphical representation of electrical systems like distribution systems, control panels, transmission line, generating stations, etc. is very important to understand the connections of various system components, designing and analyzing electrical systems, and more. In the field of electrical engineering, the following two main types of visual representations are ... Read More
A smart meter is an electrical instrument used for measuring electrical energy consumed and other electrical parameters of the electricity supply system. It is basically a type of energy meter equipped with more advanced metering technologies. The main advantage of using a smart meter is that it does not require any manual reading system for billing and other purposes. Instead, it can automatically send the data through communication channels to the electricity company. Therefore, smart meters help in reducing the operational cost and time. In this article, we will explain the major advantages and disadvantages of smart meters. Before ... Read More
