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).

The learner will use the ANSI Insert Identification System to identify and select carbide tools.

In this learning activity you'll define and explain the broad steps in achieving quality in an organization.

Students examine the drain curves for a JFET. They are also introduced to vocabulary terms and formulas.

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.

The learner views the operation of a transistor switching from saturation to cutoff. A brief quiz completes the activity.

Students read an introduction to the Metal Oxide Semiconductor Field Effect Transistor. They also examine its enhancement mode.

The learner solves for Zin(base), Zin(stage), Zout, and Av. A "help" screen is available.

In this animated activity, learners view the seven steps that are used to calculate voltage and current values throughout a common-emitter transistor amplifier.

Students read about the three main classes of amplifiers and view graphical representations of the collector current and circuit.

The ohmic region of the E-MOSFET is identified. Formulas are given to determine the proper operation in the ohmic region. An example of circuit analysis is also given.

Learners analyze a base-biased npn transistor circuit. A "help" screen is available.

Learners examine how melting, vaporization, and sublimation require energy input while freezing and condensation release energy.

Students read about the four steps to creating an ac model and view examples.

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.

Learners view the operation of an NPN transistor in the active region.

Students review logarithms as they pertain to electronics.

The learner solves for Zin(base), Zin(stage), Zout, and Av. A "help" screen is available.

Students view drawings of the emitter resistor bypass capacitor.

Students read about decibel power gain and decibel voltage gain. Examples are given for each.
