The Mathematical Expression of an AC Sine Wave As a Function of Time: Practice Problems
Students view the mathematical expression of a sinusoidal waveform with respect to time (t) and solve five problems. The answers are provided so students may check their work.
Evaluating Sources for the Technical Research Report
Students view information taken from various sources and decide if the material is acceptable for a technical research report. After choosing whether or not the source material is acceptable, the students read an explanation from the instructor.
Learners view illustrations showing the direct dependence of the volume of a gas on temperature and consider the relationship between the Kelvin and Celsius temperature scales.
In this animated object, learners examine formulas for displacement and velocity ratios. They also view examples and calculate velocity and the velocity ratio.
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 examine the relationship of individual parts in an assembly drawing. Assembly drawing notes, fabricated and purchased parts, and sectional views are explained briefly.
