In this animated lesson, learners examine the rectifier circuitry in a DC variable speed drive that supplies the voltages to the field coil and armature.

In this animated object, learners examine how a Hall-effect sensor operates. A short quiz completes the activity.

In this simulation activity, procedures are performed to properly align the shaft of an electric motor that replaced a defective motor, with the shaft coupling of a pump to which it is attached.

By playing a game of tic-tac-toe, a student can review what happens to currents and voltages throughout a parallel LC circuit when the applied frequency is increased above resonance.

In this animated lesson, learners follow the steps required to read the phase shift difference in degrees between two AC waveforms.

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.

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