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 review logarithms as they pertain to electronics.

Students view drawings of the dc analysis of a voltage-divider biased NPN transistor.

Students view drawings of the emitter resistor bypass capacitor.

Students read an explanation of the common-source and source-follower amplifiers. Gain formulas are developed and an example is given.

Students view a dc analysis of an emitter-biased NPN transistor.

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

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

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.

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

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

Students view a dc analysis of a base-biased NPN transistor.

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

Students read the terms associated with the Bipolar Junction Transistor (BJT) . They also view formulas for dc current and voltage.

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

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

Students view the design and function of an ac model for a transistor circuit.

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