In this animated and interactive object, learners examine why the voltage produced by an AC drive must be increased when its frequency is increased due to inductive reactance.

Learners examine devices that are used to protect a motor from damage, such as fuses, overload heaters, and thermal protectors. A quiz completes the activity.

In this interactive object, learners solve for total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated by each resistor.

In this interactive object, learners use the Law of Cosines to calculate forces.

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.

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.
