In this animated activity, learners examine the operation of an ultrasonic sensor and the procedure to perform zero and span adjustments. A brief quiz completes the object.
Op Amp Comparator
By Terry Bartelt
Students read an explanation of the operation of an operational amplifier that functions as a comparator.
Parallel LC Circuit Tic-Tac-Toe 1
By playing a game of tic-tac-toe, a student can review what happens to currents and voltages throughout a parallel LC circuit when the applied frequency increases from 0 Hz toward resonance.

In this interactive object, learners examine sectional views used in engineering drawings. The sections shown are full, half, offset, aligned, revolved, and broken-out. Learners match drawings of sectional views with the names of the views.
Rotating Vector Representation of the Sine Function
The learner will be able to represent steady-state AC sinusoidal signals using phasors, which will lead to a simplified technique of analyzing AC circuits in a very similar way that we analyze DC circuits.
By Rosie Bunnow
Learners practice revising poorly written directions by applying criteria for giving directions.
Displacement Level Sensors
In this animated object, learners study how displacement level sensors are used to measure the level of liquid in a tank.
In this animated object, learners observe the operation of a J thermocouple with a cold junction. A table is used to convert the voltage it produces to a corresponding temperature. A brief quiz completes the activity.
By John Casey, Terry Bartelt
In this animated learning object, learners examine how an ultrasonic flowmeter measures the flow of liquids through a pipe using ultrasonic sound waves. A short quiz completes the activity.
Incremental Encoder Quadrature Modes
Learners study the method of using more than one track and quadrature modes to improve the resolution of an optical encoder. A brief quiz completes the activity.
