In this interactive object, learners solve for total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated by each resistor.

Learners read how the transfer function for a RL high pass filter is developed. The transfer function is used in Excel to graph the Vout. The circuit is also simulated in Electronic WorkBench, and the resulting Bode plot is compared to the graph from Excel.

In this screencast, learners read an explanation of the color code used on schematic diagrams for hydraulic circuits. Circuit examples for each color are shown.

Learners view animations showing how to change the connections to cause a DC motor to reverse its rotation. A short quiz completes the activity.

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 follow the steps for adding and subtracting signed numbers and complete practice exercises.

Learners follow step-by-step instructions for using an oscilloscope to measure DC voltages.

Learners read a description of how an oscilloscope is used to measure the frequency of a sine wave.
