In this lesson, students build two circuits and explore how transistors function. When Bell Labs introduced the transistor in June of 1948, a spokesman proudly announced "This cylindrical object . . .

IGBT, stands for Insulated Gate Bipolar Transistor. It is a bipolar transistor with an insulated gate terminal. It combines a control input with a MOS structure and a bipolar power transistor in a ...

Building things in a lab is easy, at least when compared to scaling up for mass production. That’s why there are so many articles about fusion being right around the corner, or battery technology that ...
