Learners observe how an optical pyrometer is used to take temperature measurements without making physical contact with the object being measured.

In this animated activity, learners examine how an adjustable pressure-reducing valve can produce a pressure that is lower at its output than at its input.

Learners examine the correct method for calculating complex reciprocals. The solution for total impedance of a parallel circuit in rectangular form is shown.

Students view the equations used to determine the ac parameters of the transistor circuit.

Learners examine how the load resistance connected to the secondary coil of a transformer affects the primary current. A brief quiz completes the activity.

Learners view animations and video clips showing how power is transmitted from one energized coil to another.

Students solve practice problems on voltage, current, and impedance matching. Examples precede the problems.

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.
