Basic DC Circuit Theory | Chapter 1

A DC voltage is a voltage that produces, or would produce, DC current, and an AC voltage produces or would produce AC current—and this introduces another terminology problem. "DC" and "AC" are sometimes attached to the word "current," even though these phrases mean "direct-current current" and "alternating-current current."
