Main Page | See live article | Alphabetical index AC/DC is an Australian rock band whom some claim to have invented hard rock. In electrical engineering, a power supply is said to be AC-DC if it can accept both alternating current (AC) and direct current (DC). By analogy with the electrical sense, AC-DC is also a slang term meaning bisexual. Also, "AC/DC" was thought by some to stand for "anti-christ, devil child". This article is from Wikipedia.
