Students read the multivariable theorems and view the graphic depictions of the Boolean expressions.
Transistor DC Analysis Practice Problems: Circuit #3
By Patrick Hoppe
Learners analyze an emitter-biased npn transistor circuit. A "help" screen is available.
Summing Op Amp
By Terry Bartelt
In this animated object, learners examine the operation of a summing operational amplifier through formulas, tables, and animated illustrations. A brief quiz completes the activity.
In this animated object, students observe how the pulsating DC output voltage of a full-wave rectifier is filtered by a capacitor.
Power Factor: A Mechanical Work Analogy
By Roger Brown
Learners read an analogy comparing mechanical work (in this case, sliding a weight) to that of electrical power. The relationship of work, apparent work, and power factor is developed.
Right Triangles That Are Special: Using the Pythagorean Theorem
By Michele Williams
In this learning activity you'll apply the Pythagorean Theorem to isosceles and equilateral triangles.
Superposition Theorem with Complex Numbers
Students read an explanation of "superposition" as a technique for ac circuit analysis. Complex numbers are used.
Total Impedance of a Parallel Circuit Using Complex Numbers
Students read how to determine the total impedance of a parallel circuit using complex numbers. The "J" term is used in the calculations.
Total Impedance of a Series Circuit Using Complex Numbers: Practice Problems
Students solve six problems for series impedance using complex numbers. Immediate feedback is given.
Total Impedance of a Parallel Circuit Using Complex Numbers: Practice Problems
Students work six practice problems to determine the total impedance of a parallel circuit.
