The Function Generator: Frequency Control

By Terry Bartelt

Learners read how to use the knobs and the output terminals of a Wavetek Model 25 function generator to obtain a waveform at a desired frequency.

Total Impedance of a Series Circuit Using Complex Numbers

By Patrick Hoppe

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.

Exclusive-OR Gates

In this learning activity you'll explore how an Exclusive-OR gate operates by using a truth table, a Boolean Algebra equation, a switch analogy, and a written statement.

Electromagnets

Learners examine how an electromagnet is formed. Animated illustrations show current running through a coil wrapped around an iron core.

Statics: Scalar vs. Vector

By Steve Whitmoyer

Learners read an introduction of scalar quantity and vector quantity and force. Examples are given.

Repetitive Cylinder Cycling

In this animated activity, learners examine the operation of a pneumatic cylinder that continuously cycles by extending and retracting.

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.

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.

Statics: Resultant Calculations via Graphical Method

In this interactive learning object, students calculate a resultant of multiple forces acting in a concurrent, coplanar condition.

Graphical BJT/JFET Transistor Biasing

By Roger Brown

Learners use two calculations to prepare a graphical solution to the biasing of bipolar junction transistors and junction field effect transistors. This method eliminates the problem of having to re-calculate the operational Q point when dealing with hard saturation.

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.

Excel: Entering a Formula

In this animated learning object, users view the process of entering a formula in an Excel spreadsheet. Several different methods and associated examples are given.

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.

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.

Op Amp Fundamentals: The Non-Inverting Amplifier

Students are introduced to the non-inverting amplifier configuration. The formulas for closed loop gain and bandwidth are shown, and an example is given.

Phase-Splitting of Single-Phase Motors

By Terry Bartelt, Terry Fleischman

The learner will understand the two methods used to create a phase shift in current between two windings.

Voltage Divider Rule Practice Problems

Learners review the VDR and work six problems. Immediate feedback is given.
