Which type of current is primarily used by most household appliances?

Most household appliances primarily use Alternating Current (AC) due to its efficiency in power distribution and ease of voltage transformation. AC can be easily converted to different voltage levels using transformers, making it suitable for long-distance transmission. This capability allows electrical utilities to generate power more efficiently and deliver it over large distances without significant losses.

Additionally, many devices, such as refrigerators, air conditioners, and lighting fixtures, are designed to operate with AC, as it is the standard form of electricity provided by utility companies. This widespread availability of AC power simplifies the integration of various appliances into household systems.

While some appliances, such as batteries or electronic devices, may use Direct Current (DC), the majority of residential electrical systems and appliances are built around AC for its advantages in safety, efficiency, and adaptability in modern electrical grids.
