AC current alternates direction, unlike DC current. Its main advantage is voltage transformation using transformers for efficient energy transmission.
AC current, or Alternating Current, is a type of electric current that periodically reverses direction. Unlike Direct Current (DC), AC does not flow in one constant direction but alternates back and forth. The main advantage of AC current is its ability to be easily transformed from high voltages to low voltages using transformers, reducing energy loss during transmission.
