Sine Wave Fundamentals: Practice Problem #10
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.
Impedance: Parallel to Series Conversion
Students view the formulas to be used to convert a parallel impedance to a series impedance.
Sine Wave Fundamentals: Practice Problem #8
Total Impedance for Series-Parallel Circuits Using Complex Numbers
Students follow the steps for finding the total impedance for a series-parallel circuit. Several examples are given.
Sine Wave Fundamentals: Practice Problem #6
The Inductive Kick of an Inductor
By Terry Bartelt
In this animated activity, learners study the principle behind an inductor producing a high momentary voltage while its magnetic field collapses. A short quiz concludes the lesson.
AC Current Flow
In this interactive and animated object, learners examine the flow of electron current into and out of hot and neutral sockets during each alternation of an AC waveform. A brief quiz completes the activity.
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.
Sine Wave Fundamentals: Practice Problem #5
Sine Wave Fundamentals
Learners examine the characteristics of a sine wave and the various ways to describe it including Vp, Vp-p, Vrms, Vavg, and frequency.
