This learning object introduces the three approximations of a diode.
A Sample Exam for Digital Electronics
By Patrick Hoppe
Students answer 10 questions in a sample exam. This exercise covers number systems, number conversion, logic gates, and combinational design. Feedback is provided.
Series-Opposing Zener Diodes
By Terry Bartelt
In this animated and interactive object, learners examine the voltages that develop across two series zener diodes, which are connected in opposite directions, when DC and AC voltages are applied across them. A brief quiz completes the activity.
Simple Pneumatic Circuits
Learners examine the operation of five pneumatic animated circuits that use directional control valves, pilot lines, check valves, needle valves, and cylinders.
The Vertical Portion of the Sine Wave
In this animated lesson, learners examine sine waves and alternating current. A brief quiz completes the object.
The Basic Operation of a Diode
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
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.
