In this interactive object, learners solve for total resistance, total current, the current through each resistor, the voltage across each resistor, and the power dissipated by each resistor.

Learners use the National Electrical Code to determine the size of a motor overload protection device.

Students examine AutoCAD toolbars and toolbar commands. They then test their knowledge in a matching exercise.

Learners follow steps for reading a P&ID diagram of a closed-loop circuit.

Learners read a description of how an oscilloscope is used to measure the frequency of a sine wave.

In this animated lesson, learners follow the steps required to read the phase shift difference in degrees between two AC waveforms.

In this animated and interactive object, learners use rotational input velocity to determine the linear output velocity of a rocker or lever. Learners test their knowledge in an exercise at the end of the activity.

In this animated object, learners examine the operation of various circuits that are internal to the inductive proximity sensor.

Learners examine the operation of an inductive proximity sensor in this animated object. A brief quiz completes the activity.
