Electricity & Electronics

Mastery of electrical concepts and laws is necessary to any understanding of physics and its applications. This powerhouse series—eight engaging programs covering all the essentials of electricity—is hands-on enough for both the electrical shop and the physics lab and theoretical enough for use in the science classroom.

Math in Electrical Technology is an eleven-minute video which is part of the series, Math in Technology. Math is necessary to get the job done in most technical fields, including auto mechanics, electricity/electronics, and the building trades. Each video shows real-life problem situations solved by using practical math and actual computations on the screen.

After a brief history of electronics starting with valves and vacuum tubes, this program explains the operation of semiconductors, diodes, and transistors. It covers the electronic band structure of conductors, insulators, and semiconductors; doping to boost the conductivity of n- and p-type semiconductors; the functioning of LEDs and photodiodes used in remote control devices and DVD readers; how NPN transistors work; and the action of MOSFETs, core components in the integrated circuits that control computers, phones, and all other electronic devices

Using case studies, first-rate technical expertise, and high-energy video, this six-part series helps develop hands-on knowledge and conceptual understanding in a variety of electronics fields. Viewers will learn about cutting-edge applications in health care, communications, manufacturing, automotive design, and environmental studies, while an additional episode highlights the design and construction of printed circuit boards. 6-part series, 20 minutes each.
