This document compares the pros and cons of alternating current (AC) and direct current (DC) power. AC has advantages of being easier to convert and not losing power over long distances, while DC has benefits of more control over power flow and being more suitable for portable devices and wireless technologies. However, DC is less efficient than AC due to energy lost during conversion between the two current types.
