This primer introduces the student to the key terms and concepts associated with the silicon diode.
The Open-Collector Logic Device
By Terry Bartelt
In this animated object, learners view the operation of an open-collector inverter with and without a pull-up resistor.
Transfer Functions: The RC Low Pass Filter
By Patrick Hoppe
Students read how the transfer function for a RC low pass filter is developed. The transfer function is used in Excel to graph the Vout. The circuit is also simulated in Electronic WorkBench and the resulting Bode plot is compared to the graph from Excel.
This animated lesson shows the operation of timer-on and timer-off delay relays used in ladder circuit operate.
The TI-83 Plus Calculator: Using Complex Numbers
This primer introduces the student to the correct method of entering complex numbers in both rectangular and polar form.
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.
