Learners analyze a base-biased npn transistor circuit. A "help" screen is available.

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

Learners examine a 555 integrated circuit, which functions as a one-shot monostable multivibrator, and then test their knowledge. Immediate feedback is provided. Animations are used to show the sequential operations.

In this animated and interactive object, learners calculate the maximum velocity of the work stroke and the return stroke.

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.
