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.

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.

In this learning activity you'll examine how electronic converters convert between analog voltages and proportional digital signals.

In this animated object, learners examine an analog closed-loop feedback system that uses potentiometers to control the position of a gear rack.

Learners compare animations of analog and digital data signals. A short quiz completes the activity.

Students follow the procedure to measure voltage with an analog voltmeter. They examine the use of the Function Switch and the Range Switch. A brief quiz completes the activity.

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.

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.

Learners read an explanation of how to troubleshoot a faulty digital-to-analog converter that has a shorted input.

Learners examine the function of the analog wattmeter to measure true power, how it is connected in a circuit, and how the internal components develop a measurement. A brief quiz completes the activity.

In this animated lesson, students read an analogy comparing water in a "special" water tank to the current "flow" through a capacitor.

Learners read an analogy comparing mechanical work (in this case, sliding a weight) to that of electrical power. The relationship of work, apparent work, and power factor is developed.

Learners read an analogy comparing an electrical transformer to mechanical gears.

In this animated object, learners view a race of two boats as an example of how the derivative function of a PID controller shortens the time duration of an operation.

Learners view the steps for testing a capacitor with an analog ohmmeter. A brief quiz completes the object.

In this learning activity you'll follow the process of converting digital data into a series of analog signals.

Learners examine eight different kinds of faulty logic or perception that interfere with critical thinking. They are superstition, ignorance, clustering illusion, false analogies, gambler’s fallacy, irrelevant comparisons, post hoc fallacy, and slippery slope fallacy. In an interactive exercise, learners identify ways to overcome these barriers.

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.
