Walk through the subscriber loop and learn how the signal travels from the central office to the subscriber.

The approach to dc circuit analysis is presented to the learner. The approach is demonstrated for the student.

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.

Learners solve word problems involving basic mechanical principles such as torque, horsepower, work, and power. Students who have problems with a particular word problem may try it again with a different set of numbers.

Learners work problems to make conversions between RMS, average, peak, and peak-to-peak AC voltages.

In this interactive object, learners examine the neuron pathway into and out of the spinal cord. They complete the activity by testing their knowledge of vocabulary and the location of spinal cord structures.

In this animated object, learners examine the function and location of the motor neurons and the damage that can result when they are injured.

In this animated object, learners examine how the sensory, motor, mixed, and reflex nerves work in the human body.

Students answer five questions concerning magnetism.
