What is the standard voltage for most household circuits in the United States?

The standard voltage for most household circuits in the United States is 120 volts. This voltage level is utilized for the majority of general-purpose circuits within homes, powering everyday appliances and fixtures such as lights, televisions, and kitchen equipment. The 120-volt system is standardized to offer a balance between safety and functionality, providing sufficient power for typical household needs while minimizing the risk of electrical hazards.

In contrast, other voltage levels mentioned, such as 240 volts, are used in specific applications, typically for larger appliances like dryers and stoves, where more power is required. Volts like 380 and 60 are not common in typical residential settings. Recognizing that the primary voltage standard in residential environments is 120 volts is crucial for understanding household electrical systems and safety practices.
