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.

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.

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.

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

In this learning activity you'll explore the operation of a NAND gate using a truth table, a Boolean Algebra equation, a switch analogy, and a written statement.

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.

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 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.

Students view drawings of the emitter resistor bypass capacitor.

In this animated and interactive object, learners examine how changes in applied voltage affect the current and voltages in a zener diode voltage regulation circuit. A short assessment completes the activity.

Robotic welding is an increasingly popular tool used in industrial welding applications. Knowing how to program the robot is key. Explore how to improve your programming skills by using calls and unconditional jumps in this learning activity.

In this animated activity, users examine the causes of malfunctions in a hydraulic pressure-reducing valve and the problems that result. A short quiz completes the learning object.

In this animated activity, learners examine the construction of a binary counter using a JK flip-flop. The ability of the JK flip-flop to "toggle" Q is also viewed.
