What is 120V?

120V (120 Volts) refers to a standard voltage level commonly used in residential and light commercial electrical systems, particularly in North America. It is the nominal voltage supplied by power companies to homes and businesses. This voltage is used to power a wide range of appliances, lighting, and electronic devices. The actual voltage may vary slightly depending on the power grid load and local regulations.
