Learners view a demonstration showing that line-neutral voltages and line-line voltages are not in-phase with each other, but have a definite 30-degree relationship.
Average Voltages of Pulsating DC Voltages
By Terry Bartelt
In this learning activity, learners will learn to calculate the average voltage produced by half-wave and full-wave rectifiers.
Abbreviations Representing Electrical Quantities
In this learning activity you'll identify abbreviations that represent quantities associated with electrical circuits.
Sine Wave Fundamentals: Practice Problem #6
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.
Basic Elements of Dimensions Used in Engineering Drawings
By Glenn Sokolowski
In this interactive object, students explore the basic elements and common terms associated with dimensions and leaders. A quiz completes the activity.
Parts of Speech in Sentences: The Order of Operations
By David Hardgrove
Learners identify the parts of speech by following a certain order until each word in a sentence is labeled. In a variety of exercises, learners practice finding verbs, prepositional phrases, subjects, nouns, pronouns, adjectives, adverbs, and conjunctions.
Transfer Functions: The RC High Pass Filter with Bode Plot
Students view the development of the transfer function for a RC high pass filter. They also read how a Bode plot is developed through simple approximation techniques for both the magnitude and phase.
The Edison Wire System
Learners read a description of the wiring configuration of a residential Edison Wire System, which consists of a transformer secondary circuit. The circuit supplies two 115-volt sources and one 230-volt source.
Oscilloscope Phase Shift Measurements
In this animated lesson, learners follow the steps required to read the phase shift difference in degrees between two AC waveforms.
The Transfer Function and Frequency Response of a Low Pass Filter
Students learn how to predict how circuits will respond to varying frequency. They solve for the magnitude and phase angles.
