The first Junction transistor was invented in 1947 at the Bell Telephone Laboratories by Dr. William Schockley and his co-inventors Dr. John Bardeen and Dr. Brattain. Transistor is capable of amplifying electronic signals such as radio and TV signals. This chapter discusses the construction of Bipolar Junction Transistor (BJT), its working and its characteristics. The amplification property of BJT and its configurations are also discussed.

The main application of semiconductor diode is in rectification; to convert ac to dc. Rectifiers are the basic building blocks of dc power supplies. Zener diode, which is designed to operate in reverse biased condition, is used as a voltage reference in voltage regulators. Diodes are also used in clipping and clamping operations.

The term diode denotes a two electrode device. Di means two and ode means electrode. A semiconductor diode is a two layer single junction two terminal unidirectional device. The current in a diode is contributed by both holes and electrons. Diode is the simplest of all semiconductor devices but plays a very important role in electronic systems. Diodes are used in variety of applications including communication systems, radio, TV, computers, power supplies and so on.

The basic principle of operation (electromagnetic principle) of a DC machine and a AC machine are the same though they differ widely in their operational characteristics. The excellent control characteristics has made the DC motor to be accepted as an industry standard. The series motor with its high starting torque finds application in traction, cranes and hoists while the shunt motor with its constant speed characteristics and development of medium torque, finds application in operation of lat

A generating station essentially employs a prime mover coupled to an alternator for the production of electric power. The prime mover converts energy available in different forms such as pressure head of water, chemical energy of fuels (either in solid, liquid or gaseous form), kinetic energy of blowing winds and nuclear energy of radio active substances into mechanical energy. The alternator converts mechanical energy of the prime mover into electrical energy.

Electric power is produced at the power generating station, which are generally located far away from the load centres. The power is delivered to the consumers through a transmission network. High voltage transmission lines are used to transmit bulk electric power from the generating station to the load centres over long distances.

A rotating electrical machine consists of an armature in which conductors are placed and connected systematically, to generate the ‘working emf’. The arrangement of conductors and their inter connections are known as ‘windings’. In synchronous machine and induction motor, the stator is the armature, which, usually, is wound for three phases, separated by 120 electrical degrees to generate the given number of poles.

Any rotating electrical machine consists of stator, rotor, end shields, fan and ventilating system, bearing system and mounting system. In a DC machine, the stator consists of a yoke which houses poles attached to the yoke and the field windings. The rotor consists of armature with supports, commutators and bearings. The armature has slots in which the windings are placed. The winding terminals are connected to the commutator.

Electrical engineering deals with the generation, transmission, and distribution of electric energy. This form of energy is preferred because it can be - (i) efficiently and economically generated in bulk, (ii) transmitted over long distances efficiently and distributed to a large number of consumers at high speed, and, (iii) easily converted to other useful forms of energy needed by the consumer in different applications.

A large number of basic laws of nature in engineering mathematics, applied sciences etc., appear mathematically in the form of differential equations. The differential equations is the general goal of differential and integral calculus and the theory of differential equations has a very important role in mathematics for understanding physical sciences.

In this chapter we establish a few reduction formulae for integrals, double and triple integrals, special functions like Beta and Gamma functions and simple problems with standard limits, which have applications in physical and engineering problems and has great practical importance.

The students who are admitted to second year through lateral entry scheme are supposed to be familiar with the notions of limits, continuity and the process of differentiating functions of a single independent variable. Therefore, in this chapter we shall continue our discussion with Successive Differentiation, Polar Curves, Taylor’s Series, Maclaurin’s Series and Partial Differentiation with some solved problems.

The real number system was known to mathematicians in the past that was used to solve algebraic equations. It therefore became necessary to extend the real number system to obtain necessary solutions to simple equations like x2+1 = 0, which could not be solved in the domain of real number. The equation becomes solvable if we introduce new quantities- square roots of negative number. An Italian mathematician Cardano first introduced square roots of negative numbers in the 16th century.

Energy exists in different forms such as kinetic energy, heat energy, electrical energy and so on. In practice, it is required to convert one form of energy into another form. A device which converts the available form of energy into the required form is known as a prime mover.

About one hundred years ago, people would have completed their daily routine work without moving more than ten kilometers radius from the place where they used to live. The reason is obvious as the daily needs like cooking, lighting, eating, etc. were largely met from the resources within this radius.
