Learners review the three formulas for power and work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and asked to solve for power. Immediate feedback is provided.

Learners examine a series-parallel circuit and solve 14 problems related to voltage, current and power. A help screen is provided.

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

Students work six practice problems to determine the total capacitance of a series circuit. Immediate feedback is given.

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

In this interactive object, learners examine the physical facets that determine the value of a capacitor. A brief quiz completes the activity.

This learning activity presents information on how the type of material used for the dielectric of a capacitor affects the capacitor's value in farads.

Students solve problems on the determination of total capacitive reactance of series-parallel capacitors.

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