AC and DC stand for Alternating Current and Direct Current , respectively.

Meaning of AC and DC

• AC (Alternating Current): A type of electrical current that periodically reverses direction, commonly used for household power supply because it can be easily transformed to different voltages and transmitted over long distances. It follows a sinusoidal pattern and is the standard for power delivered through electrical outlets.

• DC (Direct Current): A unidirectional flow of electric charge, providing a stable voltage and current flow in one direction, typically generated from batteries, solar cells, or power supplies that convert AC to DC.

Band Name Origin

The name AC/DC for the popular Australian rock band comes from electrical terminology — "Alternating Current/Direct Current." The name was inspired when the brothers Malcolm and Angus Young saw the abbreviation on their sister Margaret's sewing machine power adapter and chose it to reflect the band's high-energy performance style.

Summary

• AC : Alternates direction periodically, used for household power.

• DC : Flows steadily in one direction, used in batteries and electronics.

• Band Name : Represents the two types of electrical power, symbolizing energy and power, chosen from an everyday electrical component.
