No, in the United States, the standard voltage for household electricity is 120 volts, not 220 volts. The frequency is 60 Hz (hertz), which is also different from some other parts of the world.
However, for appliances that require more power, like ovens or air conditioners, they might use 220 volts or 240 volts, but those are typically high-power devices connected to special outlets designed for them.
So, in most homes, you’ll find 120V outlets, but there are some appliances that might use 220V. Does that help clarify?
