Coal, Gas and Electricity is a review of statistical data available for three fuel industries in the United Kingdom: coal, gas, and electricity. Topics covered include energy planning, comparability of fuels, published energy statistics, and energy consumption. This volume is comprised of five chapters and begins by explaining the purpose of energy statistics, such as to provide figures for the total production and consumption of energy and to identify the consumption of energy in sectors of the economy. A brief summary of industry activity concerned and its organization is given in order to present a clear background understanding of how data are collected; what is being measured; the stage at which measurements are made; what the reporting units are; the channels through which returns are routed; and where they are processed. The formulation of a national energy research and development strategy in the United Kingdom is then discussed, along with the comparability of fuels and government-published energy statistics. The last chapter presents statistics on energy consumption. This book will be of interest to energy officials, statisticians, economists, and social science researchers.

The Physical Basis of Electronics: An Introductory Course, Second Edition is an 11-chapter text that discusses the physical concepts of electronic devices. This edition deals with the considerable advances in electronic techniques, from the introduction of field effect transistors to the development of integrated circuits. The opening chapters discuss the fundamentals of vacuum electronics and solid-state electronics. The subsequent chapters deal with the other components of electronic devices and their functions, including semiconductor diode and transistor as an amplifier and a switch. The discussion then shifts to several types of field-effect transistor and the production of p-n junctions, transistors, and integrated circuits. A chapter highlights the four classifications of thermionic valves commonly used in electronic devices, namely, diodes, triodes, tetrodes, and pentodes. This chapter also considers the effect of small gas introduced to the characteristics of these valves. The concluding chapters discuss some of the basic modes of operation of electronic circuits and cathode-ray tube. This edition is of great value to undergraduate electronics students.
