"120 Volt" refers to a standard voltage level used in electrical systems, particularly in North America. It is commonly used for household appliances and lighting. This voltage is part of the alternating current (AC) system, which allows electricity to flow in both directions, making it suitable for powering various devices. In residential settings, outlets typically provide 120 Volt electricity, which is safe for everyday use. Appliances like toasters, microwaves, and televisions are designed to operate efficiently at this voltage. Understanding 120 Volt is essential for ensuring proper electrical safety and compatibility with devices.
