Learners examine the three steps of a processor scan cycle.

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

Learners read about the similarities of electronic and hydraulic components and then match the schematic symbols in a drag-and-drop exercise.

Learners study the operation of the retro-reflective optical sensor, along with the guidelines that should be followed regarding the target size, reflector size, alignment, and the reflectivity of the target.

Students solve problems on the determination of total inductive reactance of series-parallel inductors.

Learners alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.

Learners alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.

This learning activity presents information on how the type of material used for the core material of an inductor affects the inductors value in henries.

In this animated learning object, students examine current, voltage, and the magnetic field strength of a series RL circuit while it is de-energizing during five time constants. A quiz completes the activity.
