In this interactive object, students calculate capacitive reactance, impedance, current, and power in parallel RC circuits.
Testing an On/Off Switch
By Terry Bartelt
In this learning activity you'll review methods for testing an on/off switch with an ohmmeter and a voltmeter.
Motor Control: Hands-on Testing and Troubleshooting Procedures for the Motor Control Lab
By Dick Dierks
Learners follow a step-by-step explanation of how to test fuses and circuit interrupting devices.
The Logic Gates
By Patrick Hoppe
Students read information about basic logic gates including the gates' names, symbols, Boolean expressions, pronunciations, and truth tables. They then complete a matching exercise.
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.
The Vertical Portion of the Sine Wave
In this animated lesson, learners examine sine waves and alternating current. A brief quiz completes the object.
The Horizontal Portion of the Sine Wave
In this animated object, learners examine cycles, frequency, Hertz, wavelengths, and periods. A brief quiz completes the activity.
Series-Parallel Practice Problems Circuit 4
In this interactive object, learners work 12 problems dealing with dc circuit analysis.
RPM of AC Motors
Learners study factors that affect the synchronous speed of an AC motor: the applied AC frequency and the number of stator poles.
The Frequency of an AC Generator
By Walter Hedges, Terry Bartelt
Learners study the factors that determine the frequency of an AC generator, such as the rotational speed of the armature or the number of stator poles.
An 80-cm-long wire is made by welding a 1.0-cm-diameter, 20-cm-long copper wire to a 1.0-mm-diameter, 60-cm-long iron wire. What is the resistance of the composite wire?
I really liked it. I have had difficulty finding problems of this nature.
