What type of current is commonly used in homes?

The type of current commonly used in homes is Alternating Current (AC). AC is the standard form of electricity supplied by utility companies for residential use because it is efficient for transmitting power over long distances. The alternating nature of AC allows it to easily transform voltages using transformers, which is essential for reducing transmission losses.

Most home appliances are designed to operate on AC because it can be easily generated and transformed, making it suitable for both high voltage transmission and low voltage consumption within homes. Additionally, AC allows for the use of simpler and more cost-effective electrical systems.

In contrast, Direct Current (DC) is commonly used in batteries and electronic devices but is not practical for home power distribution due to its limitations in long-distance transmission. Pulsating Current (PC) and Continuous Current (CC) are not standard terms used in residential electrical supply and are less relevant in the context of home electricity.
