In this interactive object, learners examine the PN sections of a diode and the diode's forward- and reverse-biased operations. A brief quiz completes the activity.

Learners examine the operation of the on-off control mode using a home heating example. A short quiz completes the activity.

In this animated object, learners observe the changes inside the DC shunt motor that could cause the motor to break apart when its field coil opens. A short quiz completes the activity.

In this interactive object, students use the Law of Sines to calculate forces.

Learners practice revising poorly written directions by applying criteria for giving directions.

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.

Learners examine the fundamental concepts of sequencer output instruction. A simulated example shows a sequencer in operation.

In this animated activity, learners examine how various NAND gate configurations and the logic signals produced throughout the circuit perform the functions of all of the other types of logic gates.
