What is the typical voltage range for residential electrical service?

The typical voltage range for residential electrical service is accurately represented by the option indicating 120/240 volts. This is the standard voltage in most residential electrical systems in the United States.

The 120 volts is often used for general lighting and receptacle outlets, while 240 volts is typically utilized for larger appliances such as dryers, ovens, and HVAC systems. This dual voltage system allows for a diverse range of electrical needs within a household.

In contrast, the other options do not reflect the standard voltage configurations used in residential settings. For example, while 110/220 volts might seem familiar, the more precise and currently used figures are 120/240 volts. Likewise, the values of 100/200 volts and 130/250 volts either understate or overstate the actual voltages utilized in typical home wiring.
