Insulators and Conductors
Electrical devices need insulators and conductors to operate safely. Electricity needs conductors to travel and insulators to contain it. In this helpful text, readers learn what materials are classified as conductors and insulators as well as how they work together in devices. Semiconductors, plasmas, and their applications are also introduced. Colorful photographs, fun fact boxes, and clear explanations make important curricular concepts accessible.
