It is often convenient to draw a schematic diagram, in which different components of the circuit are represented by the symbols conveniently used. Conventional symbols used to represent some of the most commonly used electrical components are given in Table 12.1. Table 12.1 Symbols of some commonly used components in circuit diagrams

Find the value of the unknown interior angle x in the following figures: 6.5 Angle Sum Property of a Triangle There is a remarkable property connecting the three angles of a triangle. You are going to see this through the following four activities. 1. Draw a triangle.
15.1 Introduction: Plane Figures and Solid Shapes In this chapter, you will classify figures you have seen in terms of what is known as dimension. In our day to day life, we see several objects like books, balls, ice-cream cones etc., around us which have different shapes. One thing common about most of these objects is that they all have some length, breadth and height or depth. That is, they ...
In science, you study the properties of light by drawing the ray diagrams. For example, to study the refraction property of light when it enters from one medium to the other medium, you use the properties of intersecting lines and parallel lines.
Careful observation of each stamen under a dissecting microscope and making neat diagrams would elucidate the range in shape and attachment of anthers in different flowers.
Chapter 15 Introduction to Graphs 15.1 Introduction Have you seen graphs in the newspapers, television, magazines, books etc.? The purpose of the graph is to show numerical facts in visual form so that they can be understood quickly, easily and clearly. Thus graphs are visual representations of data collected. Data can also be presented in the form of a table; however a graphical presentation ...
