In this colorful and animated activity, learners examine the four functions provided by a hydraulic reservoir. A brief quiz completes the learning object.

Learners view an animation showing how the volume of a given quantity of gas varies directly with its temperature.

Students are introduced to the non-inverting amplifier configuration. The formulas for closed loop gain and bandwidth are shown, and an example is given.

Learners answer six questions about transformers.

Learners read about the internal and external users of financial information and the kinds of information most often requested.

In this learning activity you'll read the procedures for using the vertical function of an oscilloscope and view illustrations of waveforms.

By playing a game of tic-tac-toe, a student can review what happens to currents and voltages throughout a series RLC circuit when the applied frequency is increased from 0 Hz towards resonance.

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

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 increases from 0 Hz toward resonance.
