Students solve problems on the determination of total inductive reactance of series-parallel inductors.

In this screencast, learners examine why the piston of a hydraulic cylinder extends slower than it retracts. A brief quiz completes the activity.

Learners examine an electric motor control circuit that uses a motor starter module. This activity has audio content.

Students read an introduction to capacitive reactance and view examples.

In this learning activity you'll identify the various parts of a bar graph, read and interpret its data, and calculate the data to solve various application problems.

Students read brief descriptions of atoms, molecules, elements, and compounds, and complete a matching exercise that pictures these particles and molecules as pieces of taffy.

The schematic symbols of logic gates used in digital circuits are shown.

Students read information about basic logic gates including the gates' names, symbols, Boolean expressions, pronunciations, and truth tables. They then complete a matching exercise.

In this interactive learning object, students read about the voltage and current parameters commonly found on a data sheet. A brief quiz completes the activity.

You'll learn the purpose and organization of the Filesystem Hierarchy Standard (FHS).
