Examine the components of a hydraulic system.

In this animated object, learners read about hydrostatic pressure and observe how it is used to measure the level of a material in a container.

In this interactive object, students work parallel circuit analysis problems. They solve for total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated.

Learners examine how to solve problems using the Pythagorean Theorem in Excel. Practice problems are included.

Learners read the definitions of working capital, current ratio, quick ratio, return on equity, accounts receivable turnover, and inventory turnover.

This learning activity presents information on how the type of material used for the core material of an inductor affects the inductors value in henries.

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.
