Introduction Electronic circuitry has undergone tremendous changes since the invention of a triode by Lee De Forest in 1907. In those days, the active components (like triode) and passive components (like resistors, inductors and capacitors etc.) of the circuits were separate and distinct units connected by soldered leads. With the invention of the transistor in 1948 by W.H. Brattain and I. Bardeen, the electronic circuits became considerably reduced in size. It was due to the fact that a transistor was not only cheaper, more reliable and less power consuming but was also much smaller in size than an electron tube. To take advantage of small transistor size, the passive components too were greatly reduced in size thereby making the entire circuit very small. -
35402 Electronic Circuit R TG
Electricity and Electronics Electronic Circuit Repair Introduction The purpose of this video is to help you quickly learn the most common methods used to trou- bleshoot electronic circuits. Electronic troubleshooting skills are needed to diagnose and repair several types of devices. These devices include stereos, cameras, VCRs, and much more. As mentioned, the program will explain how to diagnose and repair different types of electronic com- ponents and circuits. Viewers will also learn how to use the specialized tools and instruments needed to test these particular types of circuits and components. If students plan to enter any type of electronics field, viewing this program will prove to be beneficial. The program is organized into major sections or topics. Each section covers one major segment of the subject. Graphic breaks are given between each section so that you can stop the video for class discussion, demonstrations, to answer questions, or to ask questions. This allows you to watch only a portion of the program each day, or to present it in its entirety. This program is part of the ten-part series Electricity and Electronics, which includes the following titles: • Electrical Principles • Electrical Circuits: Ohm's Law • Electrical Components Part I: Resistors/Batteries/Switches • Electrical Components Part II: Capacitors/Fuses/Flashers/Coils • Electrical Components Part III: Transformers/Relays/Motors • Electronic Components Part I: Semiconductors/Transistors/Diodes • Electronic Components Part II: Operation—Transistors/Diodes • Electronic Components Part III: Thyristors/Piezo Crystals/Solar Cells/Fiber Optics • Electrical Troubleshooting • Electronic Circuit Repair To order additional titles please see Additional Resources at www.filmsmediagroup.com at the end of this guide. -
Capacitors and Inductors
DC Principles Study Unit Capacitors and Inductors By Robert Cecci In this text, you’ll learn about how capacitors and inductors operate in DC circuits. As an industrial electrician or elec- tronics technician, you’ll be likely to encounter capacitors and inductors in your everyday work. Capacitors and induc- tors are used in many types of industrial power supplies, Preview Preview motor drive systems, and on most industrial electronics printed circuit boards. When you complete this study unit, you’ll be able to • Explain how a capacitor holds a charge • Describe common types of capacitors • Identify capacitor ratings • Calculate the total capacitance of a circuit containing capacitors connected in series or in parallel • Calculate the time constant of a resistance-capacitance (RC) circuit • Explain how inductors are constructed and describe their rating system • Describe how an inductor can regulate the flow of cur- rent in a DC circuit • Calculate the total inductance of a circuit containing inductors connected in series or parallel • Calculate the time constant of a resistance-inductance (RL) circuit Electronics Workbench is a registered trademark, property of Interactive Image Technologies Ltd. and used with permission. You’ll see the symbol shown above at several locations throughout this study unit. This symbol is the logo of Electronics Workbench, a computer-simulated electronics laboratory. The appearance of this symbol in the text mar- gin signals that there’s an Electronics Workbench lab experiment associated with that section of the text. If your program includes Elec tronics Workbench as a part of your iii learning experience, you’ll receive an experiment lab book that describes your Electronics Workbench assignments. -

circuits and is best suited for building digital circuits. These techniques can FEATURE also be applied to analog or RF designs. The basic prototyping material is ARTICLE perfboard, such as that sold at Radio Shack. This material has holes on 0.1² (2.54-mm) centers and is available in Stuart Ball several sizes. The holes match the pin spacing on DIP ICs and many other components. You can get perfboard with plated- through pads on every hole, but I pre- fer the type without pads.

Dedication To Nadia, Dalia, Dina and Peter D.S.D To Eleanor and Caitlin R.P. v This page intentionally left blank Preface Electronic circuit design is not a new activity; there have always been good designers who create good electronic circuits. For a long time, designers used discrete components to build first analogue and then digital systems. The main components for many years were: resistors, capacitors, inductors, transistors and so on. The primary concern of the designer was functionality however, once functionality has been met, the designer’s goal is then to enhance per- formance. -
