In this interactive object, students explore the basic elements and common terms associated with dimensions and leaders. A quiz completes the activity.

This interactive object is designed to help learners memorize schematic symbols used in hydraulic diagrams. Learners quiz themselves using electronic flashcards.

Learners view practical examples of how a Hall-effect sensor is used.

Learners follow steps to convert numbers from Gray code to binary code. They then view steps to change binary values to Gray code numbers.

Learners review guidelines for the proper use of a dial caliper. Illustrations appear throughout the learning object.

The learner will define indirect measurement, identify common indirect measuring tools, and select the proper measuring tool for the situation.

In this interactive and animated object, learners examine how dc voltages develop across capacitors that are connected in series and in parallel.

Students solve practice problems on voltage, current, and impedance matching. Examples precede the problems.

Learners read a description of torque and study the factors that cause its magnitude to change. A brief quiz completes the activity.

In this learning activity you'll review the six different ways in which electricity is produced: chemical, friction, heat, light, magnetism, and pressure.

In this animated object, learners examine the operation of a demultiplexer along with the data output and select lines. A brief quiz completes the activity.

In this animated object, learners examine the concept of gear ratios. The number of teeth, diameters, and velocity relationships are discussed and calculated using linear ratio equations. A quiz completes the activity.

This learning object introduces the three approximations of a diode.

Learners examine the fundamental operation of a difference operational amplifier. A brief quiz completes the activity.

This learning activity describes the physical properties that affect the inductance, in henries, of an inductor.

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.

In this learning activity you'll explore the functions and proper operation of a digital multimeter.

This animated lesson shows how to calculate the amount of force generated by hydraulic cylinders.

In this animated activity, learners examine the three main segments of a hydraulic system: power supply, control, and output. A brief quiz completes the learning object.
