Ohmmeter Capacitor Testing
By Terry Bartelt
Learners view the steps for testing a capacitor with an analog ohmmeter. A brief quiz completes the object.
Students follow step-by-step directions on how to make mathematical calculations for a Wheatstone bridge.
Series RC Circuit Practice Problems
By James Bourassa, John Rosz
In this interactive object, students calculate capacitive reactance, phase angle, impedance, and power in series RC circuits.
Series-Parallel Circuit Analysis Practice Problems: Circuit 3
By Patrick Hoppe
In this interactive object, learners solve a series-parallel DC circuit analysis problem. Immediate step-by-step feedback is given.
The schematic symbols of logic gates used in digital circuits are shown.
Instructions on how to use and construct a truth table for digital devices are provided.
The Logic Gates
Students read information about basic logic gates including the gates' names, symbols, Boolean expressions, pronunciations, and truth tables. They then complete a matching exercise.
In this learning activity you'll review the operation of an Exclusive-NOR gate by using a truth table, a Boolean Algebra equation, a switch analogy, and a written statement.
