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.

Power Factor

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.
