Excel: Entering a Formula
By Patrick Hoppe
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
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.
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.
