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.
Power Calculations in a Series/Parallel Circuit
By Terry Bartelt
In this learning activity you'll explore various ways to calculate the power consumed in a series/parallel circuit.
De-Energizing Time Constants of an RL Circuit
In this animated learning object, students examine current, voltage, and the magnetic field strength of a series RL circuit while it is de-energizing during five time constants. A quiz completes the activity.
Ladder Circuit Labeling
Learners examine the labeling scheme used in ladder logic diagrams to identify components, wires, rungs, and rails. This activity includes self-check questions.
The TI-86 Scientific Calculator: Using the Log Function
By Patrick Hoppe
This primer introduces the student to the correct method of using the log function on a TI-86 calculator.
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.
Radio Frequency Modulation
You'll learn some concepts related to radio frequency modulation.
Vi Text Editor: Command Mode
You'll become familiar with the syntax required to operate the Vi text editor while in command mode.
