In this animated learning object, students are introduced to standard procedures, pilot actions, and pilot callouts for C-172 critical phases of flight.

Learners read about the vector diagram for a parallel RC circuit. This animated lesson presents information on current flow through each branch, total current, and phase angle.

Students follow the steps that are required to select a transformer with the proper ratings. Voltage, frequency, current, and KVA are considered.

Learners study the process of mathematically converting temperatures between the Fahrenheit and Celsius scales.

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.

Learners reflect on their thoughts, feelings, and reactions toward such listening behaviors as interrupting, selective listening, and unresponsive listening.

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.

In this animated object, learners examine the PDF (portable document format), which has become the standard file format in the printing industry for the distribution of printable documents.

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

In this animated activity, learners view the input and output leads of a JK flip-flop. They also see how it functions in each mode of operation. A brief quiz completes the learning object.

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.

Users read work instructions and view a drawing and calculations for turning on a lathe using a digital readout.

In this interactive object, learners read about the occupations that are most at risk for bloodborne pathogen exposure. They also read about the most common pathogens and how they are transmitted. This learning object is based on information from the U.S. Occupational Safety and Health Administration.

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.

In this animated activity, students view the operation of a 4-bit serial-in serial-out register. A brief quiz completes the learning object.

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

Learners practice reading prints of a hub. They identify information located on the print and calculate missing dimensions.

In this quiz you'll identify common hand tools by their function.
