This physics video tutorial provides a basic introduction into the difference between alternating current vs direct current. It explains how to calculate the rms voltage and rms current in an AC circuit as well as the peak voltage and peak current. In addition, it explains how to calculate the average power in an AC circuit. This video contains plenty of examples and practice problems.
