What is the standard voltage for most residential electrical circuits in the U.S.?

• A. 120 volts
• B. 240 volts
• C. 60 volts
• D. 480 volts

Answer: (A)

The standard voltage for most residential electrical circuits in the U.S. is 120 volts. This voltage level is used predominantly for general-purpose household outlets and lighting circuits, allowing compatibility with standard residential appliances and electronic devices. Residential properties are typically set up with a split-phase electrical system where two 120-volt lines are provided, and they can also combine to supply 240 volts for larger appliances, such as dryers and ovens. However, the everyday circuits utilized in most living areas are indeed configured for 120 volts to ensure adequate power for common devices. While other voltage levels are applicable in specific settings, such as commercial or industrial use with higher voltage systems, the 120-volt standard is directly related to the needs and safety requirements of residential environments. This is why 120 volts is the correct answer for the question regarding standard residential circuit voltage in the U.S.
