alternating current
This term describes a specific type of electrical flow used primarily for long-distance power transmission because it can be easily stepped up or down in voltage using transformers. It is most commonly contrasted with direct current (DC), which flows in a single, constant direction.
In technical and everyday contexts, the term is frequently abbreviated as AC. While the full phrase is used in formal engineering or educational texts, the abbreviation is standard in consumer electronics and electrical specifications.
