Oscilloscope Phase Shift Measurements
By Terry Bartelt
In this animated lesson, learners follow the steps required to read the phase shift difference in degrees between two AC waveforms.
Effects of a Rheostat in a Series Circuit
In this animated object, learners examine how the way in which a rheostat is connected in series with other resistors causes current and voltage to change as the resistance is varied. A brief quiz completes the activity.
Interpreting Engineering Drawings: Title and Revision Blocks
By Glenn Sokolowski
Learners examine the information on a title block and answer questions about that information in an interactive quiz.
By James Bourassa
In this interactive object, learners view various components of gears and read descriptions of them. Learners then identify the location of each of these components in a drag-and-drop exercise.
Learners apply the principles associated with Boyle’s Law. A brief quiz completes the activity.
PLC Shift Registers
By Terry Bartelt, Tom Yapp
In this animated activity, learners study how a PLC performs a shift operation. The learning object covers data movement, data entry, PLC wiring, PLC shift register introductions, and programming for a paint can operation.
Analog Position Control
In this animated object, learners examine an analog closed-loop feedback system that uses potentiometers to control the position of a gear rack.
Inductive Proximity Sensors
Learners examine the operation of an inductive proximity sensor in this animated object. A brief quiz completes the activity.
Inverting Op Amp
In this interactive object, learners examine the operation of an inverting operational amplifier through formulas, tables, and animated illustrations. A brief quiz completes the activity.
An Impedance Matching Application
Learners consider why an impedance matching transformer is needed to connect an antenna to a television.
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.
Comparing Analog and Digital Signals
Learners compare animations of analog and digital data signals. A short quiz completes the activity.
In this animated lesson, students view the operation of an electromechanical relay. A brief quiz concludes the activity.
By Patrick Hoppe
Learners are introduced to primary and secondary batteries. Examples are given.
Reading a P&ID Loop
Learners follow steps for reading a P&ID diagram of a closed-loop circuit.
Reaction Curve Tuning Example
Learners perform the steps required for the Ziegler-Nichols Reaction Curve Tuning Method. The process identification procedure is performed, calculations are made, and the proper PID values are programmed into the controller.
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 examine how various types of positive and non-positive displacement hydraulic pumps work.
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.
In this animated object, learners examine different types of pneumatic actuators, cylinders, and motors.
Learners study animation showing the operation of an AC wound-rotor motor with its external starting resistors. A short quiz completes the activity.
Learners observe how to cascade PLC counters to extend the maximum count of one counter.
The Silicon Controlled Rectifier
In this animated activity, learners examine the operation of the SCR, including how it is biased and how it is turned off. A brief quiz completes the object.
The Differentiator Op Amp
In this animated object, learners examine the circuit configuration and operation of a differentiator operational amplifier. A brief quiz completes the activity.
Students examine the full-wave rectifier. They review appropriate formulas and examples of actual circuits.
