This primer introduces the student to the key terms and concepts associated with the silicon diode.
By Patrick Hoppe
In this learning activity you'll calculate the total inductance of a series circuit.
Transistor DC Analysis Practice Problems: Circuit #2
Learners analyze a base-biased npn transistor circuit. A "help" screen is available.
The Three-Way Switching Circuit
By Terry Bartelt
In this animated object, learners examine the mechanical configuration of a three-way switch and how it operates in a circuit. They also view diagrams showing the use of an ohmmeter to determine the electrical connections.
Superposition Theorem with Complex Numbers
Students read an explanation of "superposition" as a technique for ac circuit analysis. Complex numbers are used.
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.
