A series of twenty non-fiction science readers which engages children in the world around them. What is electricity? What is static electricity? Why do batteries go flat? You can find the answers to these and other questions about electricity in Why Does Electricity Flow?
This book provides an exceptionally clear introduction to DC/AC circuits supported by superior exercises, examples, and illustrations--and an emphasis on troubleshooting and applications. It features an exciting full color format which uses color to enhance the instructional value of photographs, illustrations, tables, charts, and graphs. Throughout the book's coverage, the use of mathematics is limited to only those concepts that are needed for understanding. Floyd's acclaimed troubleshooting emphasis, as always, provides learners with the problem solving experience they need for a successful career in electronics. Chapter topics cover components, quantities and units; voltage, current, and resistance; Ohm's Law; energy and power; series circuits; parallel circuits; series-parallel circuits; circuit theorems and conversions; branch, mesh, and node analysis; magnetism and electromagnetism; an introduction to alternating current and voltage; phasors and complex numbers; capacitors; inductors; transformers; RC circuits; RL circuits; RLC circuits and resonance; basic filters; circuit theorems in AC analysis; pulse response of reactive circuits; and polyphase systems in power applications. For electronics technicians, electronics teachers, and electronics hobbyists.
A modern introduction to physics for advanced students, this work focuses on the atomic structure of the material plus the links between macroscopic and microscopic phenomena. Above all, readers learn how to explain complex physical processes using simple models. This second volume deals with the theory of electricity and magnetism, as well as physical optics as understood by the classical interaction between light and material. Electrostatics and currents are discussed in a simplified way using the electrical field and microscopic models.
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.

University Physics is designed for the two- or three-semester calculus-based physics course. The text has been developed to meet the scope and sequence of most university physics courses and provides a foundation for a career in mathematics, science, or engineering. The book provides an important opportunity for students to learn the core concepts of physics and understand how those concepts apply to their lives and to the world around them. Due to the comprehensive nature of the material, we are offering the book in three volumes for flexibility and efficiency. Coverage and Scope Our University Physics textbook adheres to the scope and sequence of most two- and three-semester physics courses nationwide. We have worked to make physics interesting and accessible to students while maintaining the mathematical rigor inherent in the subject. With this objective in mind, the content of this textbook has been developed and arranged to provide a logical progression from fundamental to more advanced concepts, building upon what students have already learned and emphasizing connections between topics and between theory and applications. The goal of each section is to enable students not just to recognize concepts, but to work with them in ways that will be useful in later courses and future careers. The organization and pedagogical features were developed and vetted with feedback from science educators dedicated to the project.
