This primer introduces the student to the key terms and concepts associated with the silicon diode.
Weight-Volume Relationships: Saturated Unit Weight
By Steve Whitmoyer
Students read how to determine and calculate the saturated unit weight for a given sample of soil or aggregate, based on the weight-volume relationship. Practice problems complete the activity.
Determining Hydraulic Cylinder Size
By Terry Bartelt
Students read how to calculate the size of a hydraulic cylinder that is required for a particular application. Mathematical formulas are provided.
Ohm's Law Practice Problems #1
By Patrick Hoppe
Learners review Ohm's Law and then work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and are asked to solve for the third.
By Glenn Sokolowski
In this interactive object, learners examine standard and metric thread specifications used in engineering drawings. In a brief quiz, they identify various internal and external thread representations.
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.
This learning object introduces the three approximations of a diode.
The Full-Wave Rectifier
Learners view the operation of a full-wave rectifier which has two diodes.
This primer introduces the student to the half-wave rectifier. Both the 1st and 2nd approximations are examined.
