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

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

In this learning activity you'll review the various ways to calculate the total power consumed in a series circuit.

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

Learners work problems to make conversions between RMS, average, peak, and peak-to-peak AC voltages.

In this animated object, learners examine the formulas used to convert peak, RMS, average, and peak-to-peak AC voltages. A brief quiz completes the activity.

Learners view animations and video clips showing how power is transmitted from one energized coil to another.

Students solve six problems for series impedance using complex numbers. Immediate feedback is given.

Students work six practice problems to determine the total impedance of a parallel circuit.
