In this animated activity, learners examine the operation of a dynamic braking circuit used to quickly stop a motor.

In this interactive and animated object, learners examine orthographic projection and the Glass Box Theory. Front, side, and top view development is demonstrated with pictorial views of each object to help develop 2D to 3D visualization skills.

Learners observe the animated operation of an astable mulivibrator using a 555 IC (integrated circuit) chip and external components.

Learners view animations showing how electrical signals are applied to the coils of a stepper motor to perform microstepping. A short quiz completes the activity.

In this interactive object, learners read the common abbreviations used in engineering drawings and then test their knowledge in three short exercises.

Learners examine the information on a title block and answer questions about that information in an interactive quiz.

The use of the reciprocal key on the TI-86 scientific calculator is demonstrated in the solution of parallel resistors.

This primer introduces the student to the correct method of entering complex numbers into a TI-86 calculator.

This primer introduces the student to the correct method of using complex reciprocals in a TI-86 calculator. The solution of total impedance of a parallel circuit in rectangular form is shown.
