In this screencast, Geometric Dimensioning & Tolerancing: The Feature Control Frame, learners examine geometric characteristic symbols, tolerances, datum feature symbols, and other control frame information.

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

In this interactive object, learners solve for total resistance, total current, the current through each resistor, the voltage across each resistor, and the power dissipated by each resistor.

Learners examine the characteristics of a sine wave and the various ways to describe it including Vp, Vp-p, Vrms, Vavg, and frequency.

Learners read how an inductor opposes a current change when it begins to energize and when it begins to de-energize. A short quiz completes the activity.

Learners compare electromagnetic quantities with the voltage, current, and resistance quantities of an electrical circuit. A brief quiz completes the object.

Learners apply the Law of Cosines to determine forces using a TI-36X calculator in this animated object.

In this interactive and animated object, learners apply the Law of Cosines to determine forces using a TI-86 calculator.

In this interactive object, students view an animated depiction of Class 1 levers. A matching quiz completes the activity.
