Electronic devices are being used in almost all the industries for quality control and automation and they are fast replacing the present vast army of workers engaged in process- ing and assembling in the factories. Great strides taken in the industrial applications of electronics during the recent years have demonstrated that this versatile tool can be of great importance in in- creasing production, efficiency and control.

The rapid growth of electronic technology offers a formidable challenge to the beginner, who may be almost paralysed by the mass of details. However, the mastery of fundamentals can simplify the learning process to a great extent. The purpose of this chapter is to present the elementary knowl- edge in order to enable the readers to follow the subsequent chapters. Electronics essentially deals with electronic devices and their utilisation.

An electronic device is that in which current flows through a vacuum or gas or semiconductor. Such devices have valuable properties which enable them to function and behave as the friend of man today. Electronics has gained much importance due to its numerous applications in in- dustry. The electronic devices are capable of performing the following functions : i Rectification. Electronic devices can convert a. The process of raising the strength of a weak signal is known as amplifica- tion.

For example, an amplifier is used in a radio- set where the weak signal is amplified so that it can be heard loudly. Similarly, amplifiers are used in public address system, television etc. Electronic devices find wide applications in automatic control.

For example, speed of a motor, voltage across a refrigerator etc. Electronic devices can convert d. The oscillators are used in a wide variety of ways. For example, electronic high frequency heating is used for annealing and hardening. Introduction 3 Fig. Photo-electric devices are used in Burglar alarms, sound recording on motion pictures etc. This valuable property is utilised in television and radar. All the materials are composed of very small particles called atoms.

The atoms are the building bricks of all matter. An atom consists of a central nucleus of positive charge around which small negatively charged particles, called electrons revolve in different paths or orbits. A proton is a positively charged particle, while the neutron has the same mass as the proton, but has no charge.

There- fore, the nucleus of an atom is positively charged. The sum of protons and neutrons constitutes the entire weight of an atom and is called atomic weight.

It is because the particles in the extra nucleus i. An electron is a negatively charged particle having negligible mass. The charge on an electron is equal but opposite to that on a proton.
