What type of current is primarily used in residential settings?

In residential settings, Alternating Current (AC) is primarily used due to its efficiency in power distribution and its ability to easily be transformed to different voltages. AC power allows for the use of transformers, which can step up the voltage for transmission over long distances and then step it down for safe usage in homes. This capability reduces energy loss during transmission and enables the use of high-voltage power lines, making AC the standard for electricity supply in most residential areas.

AC also supports a wide range of household appliances and lighting. Most electrical devices, including those commonly found in homes, are designed to operate on AC power, making it practical for daily use. In contrast, other types of current, such as Direct Current (DC), while used in certain applications (like batteries and some electronic devices), are not the standard for residential electrical systems. High Voltage Alternating Current (HVAC) refers to AC used specifically in high voltage applications and is not applicable to typical residential use, while Pulsating Current (PC) is more specialized and not commonly found in standard electrical systems. Thus, the use of AC for residential power supply is justified by its efficiency, safety, and compatibility with home appliances.
