# Electronics Practicals: real world circuits applications

## Book Preface

Circuit symbols are used for electronic circuit diagrams. The various symbols are used to represent different electronic components and devices in circuit diagrams from wires to batteries and passive components to semiconductors, logic circuits and highly complicated integrated circuits. By using a common set of circuit symbols in circuit diagrams, it is possible for electronic engineers around the globe to communicate circuit information concisely and without ambiguity. Although there are a number of different standards in use for the different circuit symbols around the globe, the differences are normally small, and because most systems are well known there is normally little room for ambiguity.

Scientific and engineering notation which are used to write numbers in compact form are represented in this chapter.

Electrical and electronics quantities of measurement are described in this chapter. These quantities are derivatives of the International System of Units. The SI base quantities make a set of mutually independent dimensions that are used in science and technology. However, in a given realization in these units they may well be interdependent, i.e. defined in terms of each other.
