Learners alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.
By Terry Bartelt
In this animated object, learners examine the operation of a Schmitt Trigger IC and its hysteresis function. A brief quiz completes the activity.
Digital Circuit Devices
The two types of digital devices, logic gates and flip-flops, and the types of basic operations they perform are presented.
Total Impedance of a Parallel Circuit Using Complex Numbers: Practice Problems
By Patrick Hoppe
Students work six practice problems to determine the total impedance of a parallel circuit.
Voltage and Resistors
By Tim Tewalt
This is an animated troubleshooting exercise that takes voltage measurements to determine the fault of three different series circuits. There are six review questions that enable the learner to determine the effectiveness of the troubleshooting presentation.
Series RC Circuit Vector and Circuit Analyzer
By James Bourassa, John Rosz
In this teaching and learning aid, the user can alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.
Inductive Reactance Practice Problems
Students solve problems on the determination of total inductive reactance of series-parallel inductors.
Parallel RC Circuit Vector and Circuit Analyzer
Parallel RL Circuit Vector and Circuit Analyzer
