Types of Energy Meters and Their Working Principles
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 MoreWhat are Automatic Voltage Regulators (AVR)?
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 MoreWhat is Floating Neutral?
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 MoreChord of a Circle, Its Length and Theorems
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 MoreCompleting the Square Method
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 MoreCone
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 MoreCuboid
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 MoreDiagonal Matrices
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 MoreArea of Quadrilateral
Introduction Area of a quadrilateral is the region enclosed by the sides of the quadrilateral. The quantity of territory contained within a quadrilateral determines its area. Let's review the definition of a quadrilateral. A closed shape with four line segments enclosing it is referred to as a quadrilateral. Both regular and irregular quadrilaterals exist. A quadrilateral with regular sides is one with equal-length sides. An irregular quadrilateral is a quadrilateral that is not regular. There are six different kinds of quadrilaterals. Square, rectangle, parallelogram, trapezoid, rhombus, kite, etc. In this tutorial, we discuss areas of all these quadrilaterals. We'll ...
Read MoreArea
Introduction Area is the space occupied by a figure. Polygons are the two-dimensional shape which has plane closed figures made of the line segments. Based on the number of sides each name of the polygon varies such as, triangles, quadrilateral, etc. The circle and ellipse are closed two dimensional shapes that have no sides. Area is a two-dimensional measurement that represents the amount of space covered by a two-dimensional shape. Area Area is the space inside a 2D shape. To measure the area of polygons, when the figure is in the grid, we can use unit squares. By ...
