Learners examine how a PLC Timer-Off instruction is used in the operation of an automotive paint booth.

In this animated object, learners examine the circuit configuration and operation of a differentiator operational amplifier. A brief quiz completes the activity.

The learner will use the deceptively simple sine bar to measure angles to minutes or even half minutes.

Students answer five questions concerning magnetism.

In this animated learning object, students view the operation of an oscilloscope that is used to measure AC voltages. A brief quiz completes the activity.

Describe the inverting op-amp configuration and calculate the circuit gain.

Learners view waveforms at various locations of an SCR circuit controlling the intensity a light bulb. The waveforms are shown when the light is dim, at medium brightness, and at full brightness. A brief quiz completes the activity.

This learning activity describes the abilities of an inductor coil to oppose alternating current and to pass direct current.

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 examine three formulas than can be used to find dc power. Examples are given.

Learners study animation showing the operation of an AC wound-rotor motor with its external starting resistors. A short quiz completes the activity.

Students view a demonstration of the Current Divider Rule with the use of complex numbers. Examples are given.

Students view a graphical explanation of how the motor condition (unloaded, 50 percent loaded, fully loaded) affects the phase between voltage and current, the current draw from the AC supply, the amount of power consumed, and the power factor.

The technique for designing a MOD 10 counter is introduced. Asynchronous inputs of a JK flip-flop are used to clear the counter.

In this interactive object, students read how to calculate the blank size for cylinders in a three-roll pinch roller. A calculator is required for the brief quiz that completes the activity.

Learners read a description of torque and study the factors that cause its magnitude to change.

Learners test their ability to visualize a three-step block in this interactive exercise that features animated pictorial views.

Students follow step-by-step directions on how to make mathematical calculations for a Wheatstone bridge.

In this animated object, students view an explanation of how current, voltage, and the charge on a capacitor of a series RC circuit change during five time constants. A short quiz completes the activity.

In this animated activity, learners examine the circuitry in a DC variable speed drive that keeps the motor running at a constant speed as the load varies.

Learners will follow general tips and tricks for improving their basic welding technique.

The learner will learn the programming steps that are used to create circular motions with robots.

In this animated object, learners follow an analogy of water flowing through pipes and valves to see how current increases in a parallel circuit as branches are added.

Introduction to selecting the proper punch and die for air bending or bottoming when forming on a press brake. Includes charts and methods for selection.

In this animated activity, learners examine the operation of normally open and normally closed valves used in hydraulics. A brief quiz completes the learning object.
