Learners view a demonstration showing that line-neutral voltages and line-line voltages are not in-phase with each other, but have a definite 30-degree relationship.

In this learning activity you'll practice solving for the total resistance of series-parallel DC circuits.

Learners examine the complex number function to convert real and imaginary coefficients into a complex number.

Learners view two animations that show the effects of eddy currents.

In this animated object, learners examine the operation of two-way, three-way, and four-way directional control valves used in pneumatic systems.

In this animated object, learners examine the fundamental operation of a noninverting operational amplifier. A brief 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.

Students read about the ideal versions of the four common filters (low-pass, high-pass, bandpass, and notch), and view graphical representations of the filters' frequency characteristics.

Students follow the correct keystrokes to calculate the logarithm of a number.

Learners examine the sourcing and sinking of conventional current at a PLC output module and the type of field device to which it is connected. This interactive learning object includes six quiz questions.

Learners read how the transfer function for a RC high pass filter is developed. The transfer function is used in Excel to graph the Vout. The circuit is also simulated in Electronic WorkBench and the resulting Bode plot is compared to the graph from Excel.

Students read how the transfer function is developed for an RC low-pass filter. A straight line Bode plot is drawn through close approximations.

Learners examine the labeling scheme used in ladder logic diagrams to identify components, wires, rungs, and rails. This activity includes self-check questions.

In this interactive object, learners use the Pythagorean Theorem to calculate forces.

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

Learners examine pictorial drawings used in engineering including sectioned and exploded drawings. A sketching quiz is provided to help the learner create simple pictorial sketches by using orthographic views and an isometric template.

In this animated object, learners study the operation of a ladder circuit that controls the rotational direction of a DC motor.

Learners examine a 555 integrated circuit, which functions as a one-shot monostable multivibrator, and then test their knowledge. Immediate feedback is provided. Animations are used to show the sequential operations.

Learners examine the operation of a DC Shunt motor and its characteristics. A quiz completes the activity.

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

Examine the components of a hydraulic system.

Learners consider why an impedance matching transformer is needed to connect an antenna to a television.

Learners read how to use the knobs and the output terminals of a Wavetek Model 25 function generator to obtain a waveform at a desired frequency.
