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 view the waveforms and voltages of an Edison Three-Wire System and read a description of the polarities across the secondary of the center-tap transformer. This transformer supplies power to residential homes.

The operation of a hydraulic brake valve, including the internal components, is presented using animations.

This learning object introduces the student to the calculations involved in a sieve analysis -- including percentage retained and percentage passed.

In this learning activity you'll create a packet filter.

In this animated object, learners observe the voltage on a capacitor at various time constants when it either charges or discharges. Students then answer questions in the categories of Identify, Compare, and Compute.

In this animated object, students view an explanation of how current, voltage, and the charge on a capacitor of a series RC circuit change during five time constants. A short quiz completes the activity.

In this animated object, learners examine how current, voltage and the discharging capacitor of a series RC changes during 5 time constants. A brief quiz completes the activity.

In this animated learning object, students examine current, voltage, and the magnetic field strength of a series RL circuit while it is de-energizing during five time constants. A quiz completes the activity.
