In this learning activity you'll read descriptions of military standards, ANSI, ISO, calibration system standards and audit system reference standards. These topics would be important for the CQT (certified quality technician).
In this animated and interactive object, learners use a memory device to identify NPN and PNP transistors. Learners also examine how much the transistors turn on when the voltage applied to the base is varied.
Transistor Fundamentals: Junction Field Effect Transistor (JFET)
Students read about the common characteristics of the Junction Field Effect Transistor. They also explore the schematic symbols and the basic operation of the JFET.
Transistor Fundamentals: Collector Saturation and Collector-Emitter Cutoff
Students read about the concepts of saturation and cutoff. They view diagrams that illustrate the interaction of the load line and the family of curves.
Learners use two calculations to prepare a graphical solution to the biasing of bipolar junction transistors and junction field effect transistors. This method eliminates the problem of having to re-calculate the operational Q point when dealing with hard saturation.
