An inverter battery is an electrochemical device that is used for storing electrical energy. It is a type of rechargeable battery that works with an inverter to provide continuous power supply in the case of main supply outages. An inverter battery charges when main power supply is available and it delivers the stored electrical power when the main power supply is disrupted. In this article, we will explain the different types of inverter batteries along with their advantages and disadvantages. But before that let us get an overview of inverter batteries and know about their specifications. What is ... Read More
This article is meant for explaining different types of electric vehicles, their construction, components, working principle, and features. A type of vehicle, a car, or a bike, or any other, that uses electricity as the source of energy to run is called an electric vehicle. Today, electric vehicles are becoming one of the most popular modes of transportation because of their sustainability, low operating cost, and eco-friendliness. Traditional vehicles operating on petrol and diesel have very high operating cost and they also pollute the environment due to emissions. Till date, several different types of electric vehicles have been ... Read More
An energy meter is a device used for measuring the amount of electrical energy consumed by a load over a certain period of time. This device is essential for recording the electricity usages so that consumers can monitor and change the energy consumption patterns to reduce energy consumption and hence the bill amount. An energy meter is an important link between power supplier and consumers that allows them for efficient measurement of electricity supplied or consumed. What is an Energy Meter? An electrical device or instrument which is used for measuring the amount of electricity consumed by the consumers over ... Read More
In electrical power system, there is a device called Automatic Voltage Regulator (AVR) used to adjust the voltage levels within a desired limit. In other words, an automatic voltage regulator is an electronic circuit that is primarily used for regulating the output voltage of an electric generator, so that we can obtain a constant voltage even when the load is fluctuating. This tutorial will explain the construction, working, needs, advantages, and applications of automatic voltage regulators (AVRs). So, let’s start with the basic introduction of automatic voltage regulator. What is an Automatic Voltage Regulator? An AVR or Automatic Voltage Regulator ... Read More
In an electrical system, there are three types of conductors used, they are phase, neutral, and ground. In general, the neutral wire is grounded for safety and stability reasons. But sometimes, a condition occurs where the neutral wire of the systems is disconnected from the ground terminal, this condition is known as floating neutral. In some special situations, the neutral wire is intentionally left isolated from the ground terminal, this is also known as floating neutral. In this article, we will learn about floating neutral in electrical systems, its effects, causes, and methods of testing and fixing the floating ... Read More
Introduction A chord is a line segment connecting any two points located on the circumference of the circle . The circle is a well-known two-dimensional shape used in Euclidean geometry. It has various components, including chord, radius, diameter, etc. In this tutorial, we will discuss the definition, formulae, and some theorems related to the chord of a circle. Circles The circle is a two-dimensional figure drawn on a plane in such a way that each point on the circle is equidistant to a fixed point. The fixed point is known as the center of the circle. The dimension of ... Read More
Introduction Completing the square is an algebraic technique for writing a quadratic expression that contains the perfect square . The Quadratic Formula is the most basic method for determining the roots of a quadratic equation. Certain quadratic equations cannot be easily factorised, and in these cases, we can use this quadratic formula to find the roots as quickly as possible. The roots of the quadratic equation also aid in determining the sum and product of the roots of the quadratic equation. The quadratic formula's two roots are presented as a single expression. The positive and negative signs can be used ... Read More
Introduction A cone has a curved surface at the bottom; therefore, it contains two surface areas that are total surface area is the total surface area covered by the cone, whereas the curved surface the area consists of the surface area covered by the curved surface, which is the surface area other than the bottom circular flat surface. A cone has a vertex or an apex and a slant height. In this tutorial, we will discuss cones, slant height, curved surface area, total surface area, and a few solved examples. Cones Cones are three-dimensional figures with a circular surface at ... Read More
Introduction A cuboid is a solid shape or a three-dimensional shape in geometry. A cuboid is an 8 vertices, 12 edges, and 6 rectangular faces convex polyhedron. A cuboid is also known as a rectangular prism. An example of a cuboid in the real world is a rectangular box. What is cuboid? Imagine a shape that results from stacking numerous congruent rectangles on top of one another. The resultant shape is known as a cuboid. Dimensions of a Cuboid In order to describe the length, width (breadth), or height of an edge of a cuboid shape, it should be ... Read More
Introduction A diagonal matrix is a matrix in which the entries outside the main diagonal are all zero. Matrices are used in practical life events like military parades, school parades, and planting. The concept of matrix and determinant is recorded as having appeared in the fourth century B.C, although its use is thought to have begun only in the second century BC. Then, towards the end of the seventeenth century, the concept of matrix and determinants came back into use. Mathematical models of everyday world problems are formed as sets of linear equations. Matrices are essential and inevitable to solve ... Read More
