Learners alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.

In this animated and interactive object, learners examine how changes in applied voltage affect the current and voltages in a zener diode voltage regulation circuit. A short assessment 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 solve for total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated.

In this learning activity you'll discover how to calculate the best priced items and improve your financial literacy.

Learners read how to use a lumber rule to quickly and accurately estimate board feet. They then use virtual samples to practice the process.

In this animated activity, students read about weight-volume relationships within a given sample of soil or aggregate. They complete problems using a 3-phase diagram.

This interactive learning object demonstrates how the moisture content is determined for a given sample of soil or aggregate.

Students read about the concept of unit weight relating to the 3-phase diagram and perform calculations.
