Op Amp Fundamentals: The Non-Inverting Amplifier
By Patrick Hoppe
Students are introduced to the non-inverting amplifier configuration. The formulas for closed loop gain and bandwidth are shown, and an example is given.
Time Proportioning Application
By Terry Bartelt
In this animated activity, students view the plastic pellets in a profile extrusion machine being melted as the temperature of the heating elements is elevated by a time proportioning control system.
What's the Point?
By Rosie Bunnow
Learners dissect a portion of a wordy document by summarizing and "chunking" related bits of information to find the important points.
Current and Voltage Parameters of Digital Circuitry
In this interactive learning object, students read about the voltage and current parameters commonly found on a data sheet. A brief quiz completes the activity.
Mathematical Expression of an AC Sine Wave
Students view the mathematical expression of an AC waveform with respect to time (t) and read about the different components of this expression.
Transfer Functions: The RC High Pass Filter
Learners read how the transfer function for a RC high pass filter is developed. The transfer function is used in Excel to graph the Vout. The circuit is also simulated in Electronic WorkBench and the resulting Bode plot is compared to the graph from Excel.
Transfer Functions: The RL Low Pass Filter
Learners read how the transfer function for a RC low pass filter is developed. The transfer function is used in Excel to graph the Vout. The circuit is also simulated in Electronic WorkBench and the resulting Bode plot is compared to the graph from Excel.
Learners read about the concepts of true power, reactive power, and apparent power, and are introduced to the power factor formula. A short quiz completes the activity.
Total Impedance of a Series Circuit Using Complex Numbers
Students view several examples of how to determine the total impedance of a series circuit. The "j" term is used in all of the calculations.
Behavior of Flexo Ink in the Two-Roll System Ink Train
By Steve Utschig
Learners examine how the two-roll metering system works.
Brain Exercise: Visualization #1
By Glenn Sokolowski
In this interactive object, learners practice their 3D visualization skills by identifying the correct isometric view of an object. Front, side, and top orthographic views are shown.
Making the Workplace Talk to You: Using Visual Controls
By Kaye Krueger
Learners examine how visual controls help to manage the workplace. Photos of visual controls are provided.
Electrical Generator Basics
In this animated activity, learners examine how a voltage is induced into a conductor when the conductor cuts across magnetic flux lines. They also view the four factors that determine how much voltage is generated. A brief quiz completes the learning object.
The DC Motor
Learners examine the wiring of the primary components of the three types of DC motors, series, shunt, and compound. The operational characteristics of each type of motor are described. A quiz completes the activity.
Excel: Rectangular to Polar Conversion for the Phase Angle in Radians
The conversion from rectangular to polar mode phase angle in radians is demonstrated in Excel.
Identifying Non-Random Patterns on a Control Chart
By Mary Lee Rudnick-Kaun
In this learning activity you'll recognize several patterns on an Xbar and R control chart. These non-random patterns are indications that the process is not in a state of statistical control.
Proportional Control Amplifier
Learners examine the operation of a proportional control amplifier and the two ways that it is programmed using proportional gain or proportional band. A brief quiz completes the activity.
Voltage Divider Rule Practice Problems
Learners review the VDR and work six problems. Immediate feedback is given.
