Books with author Dr Christopher Cooper

Modern life makes extensive use of electronics. On a daily basis, we use smartphones, computers, and TVs in the home and robots in industry and commerce. This title outlines the development of electronics, from early vacuum tubes to todays microchips. It explains how semiconductors work at the atomic level and how they are made into solid-state devices essential for the Internet and other applications. A biographical chapter on J. J. Thomson, who discovered the electron (the key to electronics), rounds out the text. Science projects readers can try at home illustrate principles of physics.

A compelling introduction to electric current, this volume investigates the conducting properties of various materials and goes on to describe ways of producing electric currents. It also describes how electricity is used in the home, in industry, and in the world of communications. Aligned to the Common Core science standards, the text explains moving charge, current and stored charge, resistance and power, direct and alternating currents, and electricity from machines, among other subjects. Nine activities help students understand practical applications. A chapter about Thomas Alva Edison honors his electric light bulb invention and the beginning of the electric age.
