Learners compare animations of analog and digital data signals. A short quiz completes the activity.
Retro-Reflective Optical Sensors
By Terry Bartelt
Learners study the operation of the retro-reflective optical sensor, along with the guidelines that should be followed regarding the target size, reflector size, alignment, and the reflectivity of the target.
P&ID Tag Numbers
Learners study the types of information letters and numbers placed inside general piping and instrumentation diagram symbols.
By Terry Bartelt, Pat Jensen
In this learning activity, we’ll explore the impact of electric shock on the human body.
The RC Time Constant
By Patrick Hoppe
Learners examine the concept of the RC time constant. The instantaneous voltage across the capacitor is calculated.
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.
Basic Internet concepts for kids
Radio Frequency Propagation
You'll focus on how radio frequencies spread under different circumstances.
