In this animated object, learners study how the internal parts of an AC synchronous motor interact with magnetic fields to cause rotation. A short quiz completes the activity.

Students examine the first and second approximations of a voltage source. A "stiff" voltage source is defined, and several examples are given.

Learners examine how to multiply the gate propagation delay by the gate power dissipation to find the speed-power product. Examples 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.

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

In this learning activity you'll describe the operation of an AND gate by using a truth table, a waveform diagram, a Boolean Algebra equation, a switch analogy, and a written definition.

The explanation and use of timing diagrams used in digital electronics to graphically show the operation of various circuits are given.

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 learning activity you'll review how an OR gate operates using a truth table, a Boolean Algebra equation, a switch analogy, and a written statement.

This game is intended for 2nd grade students. The students will complete the fact families or select the missing equation from the fact family.
