This learning object introduces the student to the calculations involved in a sieve analysis -- including percentage retained and percentage passed.

In this animated object, learners examine the operation of a thermal flowmeter used in process control applications. A brief quiz completes the activity.

In this animated activity, learners examine how the speed of a motor may change if the voltage from the power source fluctuates due to power line irregularities. This lesson has audio content.

In this teaching and learning aid, the user can alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.

In this learning activity you'll explore how units in the metric system are related to each other and practice locating measurements on a metric line.

In this learning activity you'll practice converting from one metric unit to another.

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.

This is an animated troubleshooting exercise that takes voltage measurements to determine the fault of three different series circuits. There are six review questions that enable the learner to determine the effectiveness of the troubleshooting presentation.
