In North America, the standard voltage for household appliances is 120 volts. However, some appliances, such as stoves and clothes dryers, require a higher voltage of 240 volts. In Europe, the standard voltage for household appliances is 220-240 volts.
It is important to check the voltage requirements of your appliance before plugging it in, as using an appliance with the wrong voltage can damage the appliance or even cause a fire.
