This learning object introduces the three approximations of a diode.
Voltage and Current Amplitudes in a Parallel LC Circuit
By Terry Bartelt
In this interactive object, learners examine how voltages and currents vary in a parallel LC circuit as the applied frequency changes.
Op Amp Fundamentals: The Transconductance Amplifier
By Patrick Hoppe
Students read an introduction to the transconductance amplifier. They also view formulas for voltage-to-current conversion, closed-loop input, and output impedance. An example of how R1 controls the conversion factor is given.
By Terry Bartelt, Stephen Schneider
In this animated object, learners examine the internal structure of an unloading valve. This learning object includes a video clip demonstrating the use of an unloading valve in a metal stamping application.
In this learning activity you'll describe the operation of an AND gate by using a truth table, a waveform diagram, a Boolean Algebra equation, a switch analogy, and a written definition.
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.
