Why do the lights in a house turn on when you flip a switch? How does a remote-controlled car move? And what makes lights on TVs and microwaves blink? The technology around you may seem like magic, but most of it wouldn’t run without electricity. Electronics for Kids demystifies electricity with a collection of awesome hands-on projects. In Part 1, you’ll learn how current, voltage, and circuits work by making a battery out of a lemon, turning a metal bolt into an electromagnet, and transforming a paper cup and some magnets into a spinning motor. In Part 2, you’ll make even more cool stuff as you: –Solder a blinking LED circuit with resistors, capacitors, and relays –Turn a circuit into a touch sensor using your finger as a resistor –Build an alarm clock triggered by the sunrise –Create a musical instrument that makes sci-fi soundsThen, in Part 3, you’ll learn about digital electronics—things like logic gates and memory circuits—as you make a secret code checker and an electronic coin flipper. Finally, you’ll use everything you’ve learned to make the LED Reaction Game—test your reaction time as you try to catch a blinking light!With its clear explanations and assortment of hands-on projects, Electronics for Kids will have you building your own circuits in no time.

In the past, the teaching of electricity and electronics has more often than not been carried out from a theoretical and often highly academic standpoint. Fundamentals and basic concepts have often been presented with no indication of their practical appli cations, and all too frequently they have been illustrated by artificially contrived laboratory experiments bearing little relationship to the outside world. The course comes in the form of fourteen fairly open-ended constructional experiments or projects. Each experiment has associated with it a construction exercise and an explanation. The basic idea behind this dual presentation is that the student can embark on each circuit following only the briefest possible instructions and that an open-ended approach is thereby not prejudiced by an initial lengthy encounter with the theory behind the project; this being a sure way to dampen enthusiasm at the outset. As the investigation progresses, questions inevitably arise. Descriptions of the phenomena encountered in the experiments are therefore given in the explanations. Although these were originally intended to be for the teacher's guidance they have been found, in fact, to be quite suitable for use by the student. In the explanations mathematics has been eliminated wherever possible, mechanistic descriptions of phenomena being preferred in all cases. Stress is thereby placed on concepts rather than on mere algebraic relationships. It is hoped that students of weak mathematical background will, as a result, not be prevented from following the explanations and deriving some benefit from these.

This book presents a collection of “lessons” on various topics commonly encountered in electronic circuit design, including some basic circuits and some complex electronic circuits, which it uses as vehicles to explain the basic circuits they are composed of. The circuits considered include a linear amplifier, oscillators, counters, a digital clock, power supplies, a heartbeat detector, a sound equalizer, an audio power amplifier and a radio. The theoretical analysis has been deliberately kept to a minimum, in order to dedicate more time to a “learning by doing” approach, which, after a brief review of the theory, readers are encouraged to use directly with a simulator tool to examine the operation of circuits in a “virtual laboratory.” Though the book is not a theory textbook, readers should be familiar with the basic principles of electronic design, and with spice-like simulation tools. To help with the latter aspect, one chapter is dedicated to the basic functions and commands of the OrCad P-spice simulator used for the experiments described in the book.

It Has Often Been Experienced That Students Are Required To Perform Experiments On Certain Topic Before The Relevant Theory Has Been Taught In The Class. A Laboratory Manual Which, In Addition To A Set Of Instructions For Performing Experiments, Includes Related Theory In Brief Could Help Students Understand Experiments Better.In Response Of Demand From A Large Number Of States For An Appropriate Aboratory Manual In Basic Electricity And Electrical Measurements, The T.T.T.I., Chandigarh, Has Prepared This Manual Which Has Been Tried Out In Various Polytechnics And Improved Based On The Feedback. The Basic Objective Of The Manual Is To Encourage Students To Perform Experiments Independently And Purposefully. The Manual Organises The Information To Enable The Students To Verify Known Concepts And Principles And To Follow Certain Procedures And Practices And Thereby Acquire Relevant Skills.Detailed Instructions For Carrying Out Each Experiment Alongwith Relevant Theory In Brief Have Been Given. The Objectives For Performing An Experiment Have Been Included At The Beginning Of Each Experiment. A List Of Questions Given At The End Of Each Experiment Will Help Students Evaluate His Own Understanding.The Manual Also Includes Guidelines For Students And Teachers For Its Effective Use. An Assessment Proforma Given At The Beginning Of The Manual May Be Used By The Teachers In Evaluating The Students.

Electronics is essentially an experimental subject and enables a wealth of experimental work to be undertaken at relatively low cost. In any modestly equipped electrical engineering or physics laboratory. it is possible to plan interesting experiments to study active and passive com ponents, basic circuit functions, modular encapsulations and monolithic integrated circuits. The work may range from the formal investigation of a device new to the student to the design and construction of quite advanced, modern measurement and control systems. There are few books which guide experimental work in electronics. This text aims to rectify this by giving detailed descriptions of a series of experiments all of which have been thoroughly tested by students in physics, electronics, electrical engineering and instrumentation at The Polytechnic of Central London. Moreover, several of these experiments would seem to be appropriate for the current development of interest in courses in electronics in schools because several of them have been undertaken with considerable success by first-year sixth-form students who have come to Central London for special courses. They would also assist an introductory course in electronics for students from other disciplines and have been tried out in this way at The Polytechnic.

This laboratory manual for students of Electronics, Electrical, Instrumentation, Communication, and Computer engineering disciplines has been prepared in the form of a standalone text, offering the necessary theory and circuit diagrams with each experiment. Procedures for setting up the circuits and measuring and evaluating their performance are designed to support the material of the authors' book Analog Electronics (also published by PHI Learning). There are twenty-five experiments. The experiments cover the basic transistor circuits, the linear op-amp circuits, the active filters, the non-linear op-amp circuits, the signal generators, the voltage regulators, the power amplifiers, the high frequency amplifiers, and the data converters. In addition to the hands-on experiments using traditional test equipment and components, this manual describes the simulation of circuits using PSPICE as well. For PSPICE simulation, any available standard SPICE software may be used including the latest version OrCAD V10 Demo software. This feature allows the instructor to adopt a single laboratory manual for both types of experiments.

Designed as a hands-on guide for labs, the hobbyist, or for the industry professional, this book covers instructions and methods for doing experiments with currents and magnetism. The book includes 49 separate experiments on electricity, magnetism, currents, voltage, generators, transformers, relays, alternators, resistance, gaps, and more. Each experiment covers: the object, method, result, and questions with answers on the experiment under discussion. A separate chapter at the end of the book has over 175 questions with answers to test your knowledge of electricity and electronics.

* Experiments are linked to real applications. Students are likely to be interested and excited to learn more and explore. Example of experiments linked to real applications can be seen in Experiment 2, steps 6, 7, 15, and 16; Experiment 5, steps 6 to 10 and Experiment 7, steps 12 to 20. * Self-contained background to all electronics experiments. Students will be able to follow without having taken an electronics course. Includes a self-contained introduction based on circuits only. For the instructor this provides flexibility as to when to run the lab. It can run concurrently with the first circuits analysis course. * Review background sections are provided. This convenient text feature provides an alternative point of view; helps provide a uniform background for students of different theoretical backgrounds. * A "touch-and-feel" approach helps to provide intuition and to make things "click". Rather than thinking of the lab as a set of boring procedures, students get the idea that what they are learning is real. * Encourages students to explore and to ask "what if" questions. Helps students become active learners. * Introduces students to simple design at a very early stage. Helps students see the relevance of what they are learning, and to become active learners. * Helps students become tinkerers and to experiment on their own. Students are encouraged to become creative, and their mind is opened to new possibilities. This also benefits their subsequent professional work and/or graduate study.
