This primer introduces the student to the key terms and concepts associated with the silicon diode.
By Terry Bartelt
In this animated activity, students read about the two general types of variable resistors: potentiometers and rheostats. They then answer six multiple-choice questions.
Binary to Decimal Number Conversion
By Patrick Hoppe
In this learning activity you'll practice calculating the between the binary number system and the decimal number system.
Schematic Diagram Symbols
In this learning activity you'll review various types of common components used in electronics and view their schematic diagram symbols.
Combustible Gas Detectors
Learners examine the theory of operation for a combustible gas detector. A brief quiz completes the activity.
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.
