Learners compare animations of analog and digital data signals. A short quiz completes the activity.
Magnetics AC Power Generation
By Tim Tewalt, Patrick Hoppe
Learners examine an animation that shows how an AC voltage is produced as an armature rotates within a magnetic field. Ten review questions complete the learning object.
Power Law Practice Problems #2
By Patrick Hoppe
Learners review the three formulas for power and work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and asked to solve for power. Immediate feedback is provided.
Series-Parallel Circuit Analysis: Practice Problems Circuit 1
In this interactive object, learners analyze a series-parallel DC circuit problem in a series of steps. Immediate feedback is provided.
Ground Fault Circuit Interrupters
By Terry Bartelt
In this animated activity, learners examine how ground fault circuit interrupters work and why they are an important safety feature.
Capacitor/Inductor: An Auto Analogy
By Roger Brown
Learners compare the experience of driving an auto to the circuit responses of RL (resistance/inductance) circuits and RC (resistance/capacitance) circuits. Acceleration, position, speed, and torque are graphed.
Analog and Digital Converters
In this learning activity you'll examine how electronic converters convert between analog voltages and proportional digital signals.
In this animated activity, learners examine how an electronic converter changes digital signals to analog signals. Sections of a synthesizer are identified, and the operation of a D/A converter is demonstrated.
Analog Ohmmeter Operation
Learners follow procedures for measuring resistance using an analog ohmmeter. They examine the use of the Function Switch and the Range Switch and practice reading a non-linear scale. A brief quiz completes the activity.
Analog Ammeter Operation
Students examine the procedure to measure current with an analog ammeter. The use of Function and Range switches is explored along with reading the needle position on the meter scale. A brief quiz completes the activity.
