By Keith Brindley. Starting Electronics is unrivalled as a highly practical introduction for technicians, non-electronic engineers, software engineers, students, and hobbyists. Keith Brindley introduces readers to the functions of the main component types, their uses, and the basic principles of building and designing electronic circuits. Breadboard layouts make this very much a ready-to-run book for the experimenter, and the use of readily available, inexpensive components makes this practical exploration of electronics easily accessible to all levels of engineer and hobbyist.
Other books tell readers what to do, but sometimes fail to explain why — Brindley gives readers hands-on confidence in addition to real scientific knowledge, and insight into the principles as well as the practice. All written explanations and steps are supplemented with numerous photos, charts, tables and graphs. Concepts and practical aspects are explained thoroughly with mathematical formulae and technical schematic drawings.
Each chapter introduces a concept or tool, explains the basic theory, and provides clear instructions for a simple experiment to apply the concept or tool, with quiz sections and answers, at the end of each chapter.

Knowledge and best practice in this field are constantly changing. As new research and experience broaden our understanding, changes in research methods, professional practices, or medical treatment may become necessary. Practitioners and researchers must always rely on their own experience and knowledge in evaluating and using any information, methods, compounds, or experiments described herein.

This book originated as a collection of feature articles, previously published as a series of magazine articles in the, then, leading hobbyist electronics magazine in the UK.
They were chosen for publication in book form later, not only because they were so popular with readers in their original magazine appearances, but also because they are so relevant in the field of introductory electronics — a subject area in which it is evermore difficult to find information of a technical, knowledgeable, yet understandable nature for anyone wanting to get into electronics. This book — hopefully — is exactly that. Since its original publication, and with each successive new edition, I have added significant new material to make sure it is all still highly relevant and up to date.
Without doubt, electronics is a rapidly moving area to study, but where this book has always been and still is firmly aimed — right at the very introduction to electronics — it manages to provide one of the best entries to the subject a reader can make. I hope you will agree that the practical nature of the book lends itself to a self-learning experience that readers can follow in a logical and easily manageable manner. I also hope that you enjoy your journey into electronics, because even though it is a highly technical and quite demanding subject, it should also be fun.
Enjoy Starting Electronics! The chapter is a basic introduction to electronics. It starts by looking at the basic tools readers will need side-cutters, snipe-nose pliers, soldering iron. A section on electricity follows, showing electricity as electron flow with an analogy to water flowing. Other vital ideas are covered. Next, the fact that amps, volts, ohms are standard, they are often impractical amounts, requiring smaller amounts milliamps, microamps; millivolts, microvolts or larger kilohms, megohms depending on electronics requirements.
Keywords: Tools, charge, voltage, volts, millivolts, microvolts, resistance, ohms, kilohms, megohms, current, amps, milliamps, microamps. Most people look at an electronic circuit diagram, or a printed circuit board, and have no idea what they are. One component on the board, and one little squiggle on the diagram, looks much as another. For them, electronics is a black art, practiced by weird techies, spouting untranslatable jargon and abbreviations that make absolutely no sense whatsoever to the rest of us in the real world.
Knowing just a few things, you can set about building your own circuits. You can understand how many modern electronic appliances work, and you can even design your own.
The rest is up to you. Just exactly what these are and how much they cost depends primarily on quality. Other expensive tools and equipment that the professionals often have can usually be substituted with tools or equipment costing only a fraction of the price.
Indeed, its potential reward in terms of enjoyment and satisfaction can often be significantly greater than its cost. There are many types of cutters but the most useful sorts are side-cutters. Generally, buy a small pair — the larger ones are OK for cutting thick wires but not for much else. In electronics most wires you want to cut are thin so, for most things, the smaller the cutters the better. A small pair of pliers is useful for lightly gripping components and the like.
Like side-cutters, however, these are not meant for heavy-duty engineering work. Soldering is the process used to connect electronic components together, in a good permanent joint. Power rating will usually be specified on the iron or its packing and a useful iron will be around 25watts which may be marked 25W. Electricity is a funny thing. Sure, everyone knows that electricity is a flow of electrons, but what are electrons? Have you ever seen one? Do you know what they look like?
The truth of the matter is that we can only hypothesize about electricity. Fortunately, the hypothesis can be seen to stand in all of the aspects of electricity and electronics we are likely to look at, so to all intents and purposes the hypothesis we have is absolute.
This means we can build up ideas about electricity and be fairly sure they are correct. To put it another way, any flow of electrons is electricity.
If we can measure the electricity, we must therefore be able to say how many electrons were in the flow. Think of an analogy — say, the flow of water through a pipe Figure 1. The water has an evenly distributed number of foreign bodies in it. Now, if 1liter of water pours out of the end of the pipe into the bucket shown in Figure 1. Alternatively, by knowing the number of specks of dust which have flowed through the pipe, we can calculate the volume of water.
If, for example, 25, specks of dust have flowed, then 2. The foreign bodies that make up the charge are, of course, electrons. Going back to the water and pipe analogy, flow rate would be measured as a volume of water that flowed through the pipe during a defined period of time, say 10liters in 1 minute, liters in 1 hour, or 1liter in 1 second. With electricity, flow rate is measured in a similar way, as a volume that flows past a point during a defined period of time, except that volume is, of course, in coulombs.
So, we could say that a flow rate of electricity is 10 coulombs in 1 minute, coulombs in 1 hour, or 1 coulomb in 1 second. Instead, in electricity, flow rate is called current and given the symbol I , when drawn in a diagram. Electric current is measured in amperes shortened to amps, or even further shortened to the unit: A , where 1amp is defined as a quantity of 1 coulomb passing a point in 1 second. The other important thing we need to know about electricity is flow pressure.
Returning to our analogy with water and pipe, Figure 1. Water pressure is often classed as a head of water, where the height, h , in meters, is the head.
The effect of gravity pushes down the water in the header tank, forming a flow pressure, forcing the water out of the pipe. With electricity the flow pressure is defined by the difference in numbers of electrons between two points. We say that this is a potential difference, partly because the difference depends on the positions of the points and how many electrons potentially exist.
Another reason for the name potential difference comes from the early days in the pioneering of electricity, when the scientists of the day were making the first batteries. Figure 1. Under the conditions of Figure 1. Air is an insulator or a non-conductor. Nevertheless, the battery has the potential to light the bulb and so the difference in numbers of electrons between two points terminals in the case of a battery is known as the potential difference. A more usual name for potential difference, though, is voltage, shortened to volts, or even the symbol V.
Individual cells are rated in volts and so a cell having a voltage of 3V has a greater potential difference than a cell having a voltage of 2V. The higher the voltage, the harder a cell can force electrons around a circuit. Voltage is simply a way of expressing electrical pushing power.
After all, the higher the voltage, the more pushing power the electrons have behind them, so the faster they should flow. It may be summarized by the expression:. The cell has a voltage of 2V, so the voltage applied across the substance is also 2V. The current through the substance is, in this case, 0. Upload Sign In Join.
