What is a common application of AC voltage in residential settings?

Operating appliances is a common application of AC voltage in residential settings because most household devices, such as refrigerators, microwaves, and air conditioning units, are designed to function on alternating current (AC) provided by standard electrical outlets. AC voltage is preferred for these applications primarily due to its ability to be easily transformed to different voltage levels, allowing efficient transmission over long distances and making it suitable for powering a wide variety of residential appliances.

Additionally, AC voltage allows for easier integration of various devices, ensuring that they can operate on the same circuit, as most residential electrical systems are built around AC power. This compatibility minimizes the need for complicated setups, making it user-friendly for consumers. Other options such as charging batteries, running electric vehicles, and powering industrial machines typically rely more on direct current (DC) or specialized configurations that are less common in typical home settings.
