Students read descriptions of the voltage, current, and turns ratios of the primary and secondary coils for a transformer in this interactive lesson.

Learners read an explanation of how to troubleshoot a faulty digital-to-analog converter that has a shorted input.

Using the principle of Pascal's Law, the learner will interpret the gauge readings in a hydraulic system to determine when the system is operating properly under various load conditions and when there is a defect.

In this animated object, learners examine how to align a part on the 1808 CMM.

In this learning activity you'll examine how electronic converters convert between analog voltages and proportional digital signals.

Learners examine a series-parallel circuit and solve 14 problems related to voltage, current, and power. A help screen is provided.

In this learning activity you'll review the process of solving for the total resistance in a series DC circuit.

In this learning activity you'll determine the total resistance in a DC parallel circuit.

In this interactive activity, students read about the colored stripes on a resistor and interpret the placement of those colors to determine the value of four-band resistors.
