In this learning activity you'll determine the voltages that can be topped off of a multi-resistor voltage divider that has one main power source.

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

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

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 animated lesson, learners examine sine waves and alternating current. A brief quiz completes the object.

In this animated object, learners examine cycles, frequency, Hertz, wavelengths, and periods. A brief quiz completes the activity.

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.

In this interactive and animated object, learners examine the flow of electron current into and out of hot and neutral sockets during each alternation of an AC waveform. A brief quiz completes the activity.
