  • Electromagnetism is fundamental to the whole of electrical and electronic engineering. It provides the basis for understanding the uses of electricity and for the design of the whole spectrum of devices from the largest turbo-alternators to the smallest microcircuits. This subject is a vital part of the education of electronic engineers. Without it they are limited to understanding electronic circuits in terms of the idealizations of circuit theory.

  • This introduction to electromagnetic theory emphasises on applications in electronic engineering. The book explores the relationship between fundamental principles and the idealisations of electric circuit theory. Attention is drawn to the effects of parasitic capacitance and inductance, to electromagnetic screening and to the effects of propagation delay.

  • This is a companion volume to Electromagnetism for Electronic Engineers (3rd edn.) (Ventus, 2009). It contains the worked examples, together with worked solutions to the end of chapter examples, which featured in the previous edition of the book. I have discovered and corrected a number of mistakes in the previous edition.

  • This is a companion volume to Electromagnetism for Electronic Engineers(3 rd edn.) (Ventus, 2009). It contains the worked examples, together with worked solutions to the end of chapter examples, which featured in the previous edition of the book. I have discovered and corrected a number of mistakes in the previous edition. I hope that students will find these 88 worked examples helpful in illustrating how the fundamental laws of electromagnetism can be applied to a range of problems.

  • Chapter 5, "Power supplies", covers power supplies, including how they work and how to troubleshoot problems. The power supply is an often-underrated part of a computer. Many transient problems can be related to a faulty power supply or to poor electrical supply from the local provider. Electronic components require a steady electrical current, free of surges or drops. The power supply is responsible for providing clean, constant current.
