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.

In this animated object, learners examine how a coil of wire provides more resistance to AC current flow than an uncoiled wire. This learning object contains audio.

Understand the op-amp buffer configuration and calculate basic circuit impedance.

In this animated learning object, students read about the operation of a half-wave rectifier.

In this learning activity you'll review the operation and schematic symbols of various types of switches and push buttons used for electronic circuits.

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.

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.

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.
