220 Volts refers to a standard voltage level used in electrical systems, particularly in many countries outside of North America. It is commonly used for household appliances and industrial equipment, providing a higher voltage that allows for more efficient power transmission. In contrast to the 120 Volts used in the United States, 220 Volts can deliver more power with less current, which can reduce energy loss in wiring. This voltage level is often found in devices like washing machines, air conditioners, and electric ovens, making it essential for everyday electrical needs in various regions.
