In this interactive object, students calculate capacitive reactance, impedance, current, and power in parallel RC circuits.
Logic Probe Troubleshooting
By Terry Bartelt
In this animated object, learners follow a process for troubleshooting digital integrated circuits on a printed circuit board using a logic probe.
Ladder Logic Schematic Symbol Flashcards
By John Rosz, Terry Fleischman
This interactive object is designed to help learners memorize the schematic symbols used in ladder logic diagrams. Learners quiz themselves using electronic flashcards.
Op Amps 6: Circuit Resistance for the Inverting Amplifier
By Todd Van De Hey
The learner will calculate input and output circuit resistance for the Inverting Op-Amp configuration.
Calibrating an Opposed Optical Sensor
In this animated and interactive object, learners follow three steps to calibrate an opposed optical sensor. They consider horizontal alignment, the sensitivity setting, and having an effective beam.
AC Voltage Conversion Problems
By John Rosz, Terry Bartelt
Learners work problems to make conversions between RMS, average, peak, and peak-to-peak AC voltages.
AC Voltage Conversions
In this animated object, learners examine the formulas used to convert peak, RMS, average, and peak-to-peak AC voltages. A brief quiz completes the activity.
