Learners compare animations of analog and digital data signals. A short quiz completes the activity.
PLC Shift Registers
By Terry Bartelt, Tom Yapp
In this animated activity, learners study how a PLC performs a shift operation. The learning object covers data movement, data entry, PLC wiring, PLC shift register introductions, and programming for a paint can operation.
The Three-Way Switching Circuit
By Terry Bartelt
In this animated object, learners examine the mechanical configuration of a three-way switch and how it operates in a circuit. They also view diagrams showing the use of an ohmmeter to determine the electrical connections.
Kirchhoff's Current Law - Parallel Circuits
By Patrick Hoppe
In this learning activity you'll explore Kirchhoff's Current Law and view examples of its application.
Parallel RC Circuit Practice Problems
By James Bourassa, John Rosz
In this interactive object, students calculate capacitive reactance, impedance, current, and power in parallel RC circuits.
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.
Radio Frequency Propagation
You'll focus on how radio frequencies spread under different circumstances.
