In this interactive object, learners determine the Vp, Vp-p, Vrms, Vavg, and the frequency of a sine wave that is displayed on an oscilloscope screen.

This learning activity uses a water pressure analogy to present the concept that voltage pressure is required to cause current flow.

In this interactive object, students explore the basic elements and common terms associated with dimensions and leaders. A quiz completes the activity.

Learners study the operation and characteristics of an incremental optical encoder used in automated manufacturing applications. A brief quiz completes the activity.

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

In this animated object, students view diagrams of the UJT as it is used in the relaxation oscillator circuit. Waveforms illustrate how the circuit operates through several time periods.

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