This learning object introduces the three approximations of a diode.
Electric Pencil Sharpener: Process Planning
By Amy Gau
Students view photos of an electric pencil sharpener as it is disassembled. The learning object is intended to prepare students to be able to identify the components and create an assembly process in a future activity.
The Broadband Telco Services Subscriber Loop
Walk through the subscriber loop and learn how the signal travels from the central office to the subscriber.
Selecting a Proper Single Phase Transformer
By Gary Lindell, Terry Bartelt
Students follow the steps that are required to select a transformer with the proper ratings. Voltage, frequency, current, and KVA are considered.
Surface Texture Symbols
By Glenn Sokolowski
Learners examine the symbols and values that control surface roughness, waviness, and lay. A brief quiz completes the object.
The Basic Operation of a Diode
By Terry Bartelt
In this interactive and animated object, learners examine the operation of a semiconductor diode when it is forward and reverse biased. A brief quiz completes the activity.
The Zener Diode: Practice Problems
By Patrick Hoppe
Students complete 10 practice problems. These deal with the determination of series current, zener current, and load current, and if the zener diode is operating in the breakdown region.
Voltage Regulation of a Zener Diode
By Terry Bartelt, Terry Fleischman
The learner will understand how a zener diode maintains a constant voltage as the resistance values of a load change.
Testing a Diode
By Linda Reinke
In this interactive and animated object, learners practice testing a diode. They determine if a diode is good, open, or shorted.
The Zener Diode
In this animated object, learners examine the operation of a zener diode in the forward and reverse bias conditions. A quiz completes the activity.
