Question

The standard voltage for a home electrical outlet in the United States is 120 V. However, for high power devices, such as an electric clothes dryer, a 240 V line is often used.Why do you suppose a higher voltage is used for devices such as an electric clothes dryer?

David · Accepted Answer

High power devices, such as electric clothes driers, typically run at higher voltage than other
devices because the current is less, according to the equation I = P/V. Running with lower
current is safer because it is current, not voltage, which can cause injury or fatality.
