In the United States, the standard household voltage is
120V for most appliances, but some larger appliances like dryers, ovens, and air conditioners use
240V.
So, to clarify:
- 120V: Used in most homes for things like lights, TVs, and small electronics.
- 240V: Used for high-power appliances that require more energy, like washers, dryers, and ovens.
The
220V you mentioned is often a rough estimate for 240V, but the exact voltage can be anywhere between 220V and 240V, depending on the area.
