Learners analyze a base-biased npn transistor circuit. A "help" screen is available.
Hydraulic Cylinder Speed
By Terry Bartelt
In this interactive and animated object, learners examine why the piston of a hydraulic cylinder extends slower than it retracts. A brief quiz completes the activity.
Sine Wave Fundamentals: Practice Problem #2
By Patrick Hoppe
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.
Synchronous & Asynchronous Inputs on a JK Flip-Flop
Students examine the operation of synchronous and asynchronous inputs on a JK Flip-Flop.
Reversing the Rotation of DC Motors
By Terry Bartelt, Terry Fleischman
Learners view animations showing how to change the connections to cause a DC motor to reverse its rotation. A short 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.
Abbreviations Representing Electrical Quantities
In this learning activity you'll identify abbreviations that represent quantities associated with electrical circuits.
Voltage Divider Rule (VDR)
By Terry Fleischman, Patrick Hoppe
Students review the Voltage Divider Rule and work practice problems.
