The learner will understand the circuit configuration and operation of an integrator op amp.

Students follow the steps for finding the total impedance for a series-parallel circuit. Several examples are given.

Learners solve for voltage, current, and power in a single source, six-resistor circuit. A help screen is provided.

Students read how to determine and calculate the porosity for a given sample of soil or aggregate, based on the weight-volume relationship.

Learners read how an inductor opposes a current change when it begins to energize and when it begins to de-energize. A short quiz completes the activity.

Learners compare electromagnetic quantities with the voltage, current, and resistance quantities of an electrical circuit. A brief quiz completes the object.

Learners apply the Law of Cosines to determine forces using a TI-36X calculator in this animated object.

In this interactive and animated object, learners apply the Law of Cosines to determine forces using a TI-86 calculator.

In this interactive object, students view an animated depiction of Class 1 levers. A matching quiz completes the activity.
