Learners follow step-by-step instructions for using an oscilloscope to measure DC voltages.
Transistor AC Analysis Practice Problem: Circuit #3
By Patrick Hoppe
The learner solves for Zin(base), Zin(stage), Zout, and Av. A "help" screen is available.
Tooling Around With Toolbars
By Jeffrey Laurich, Craig Black
Students examine AutoCAD toolbars and toolbar commands. They then test their knowledge in a matching exercise.
Strength of Materials: The Centroid of a Semicircle
By Steve Whitmoyer
In this animated and interactive object, learners calculate the area and centroid of a semicircle.
By Terry Bartelt
In this animated activity, learners examine how an electronic converter changes digital signals to analog signals. Sections of a synthesizer are identified, and the operation of a D/A converter is demonstrated.
The Vertical Portion of the Sine Wave
In this animated lesson, learners examine sine waves and alternating current. A brief quiz completes the object.
The Horizontal Portion of the Sine Wave
In this animated object, learners examine cycles, frequency, Hertz, wavelengths, and periods. A brief quiz completes the activity.
Series-Parallel DC Circuits Analysis
Learners follow a methodical approach for the dc analysis of series-parallel circuits.
Series-Parallel Practice Problems Circuit 4
In this interactive object, learners work 12 problems dealing with dc circuit analysis.
Ohm's Law Practice Problems #1
Learners review Ohm's Law and then work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and are asked to solve for the third.
The Op Amp Non-Inverting Amplifier Configuration
You'll practice calculating circuit gain and output voltage for the non-inverting amplifier.
