Robotic Welding Instructions
The learner will gain an understanding of how a robot uses welding instructions to perform tasks. This learning activity includes video.
Current and Voltage Parameters of Digital Circuitry
By Patrick Hoppe
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.
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.
Electrical Generator Basics
By Terry Bartelt
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.
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.
