230 volts is a standard voltage level used in many countries for household electrical systems. It provides the necessary power for various appliances, such as refrigerators, washing machines, and lights. This voltage level is common in Europe, Asia, and Australia, making it essential for everyday electrical use. In contrast, some countries, like the United States, typically use 120 volts for residential power. The higher voltage of 230 volts allows for more efficient energy transmission over long distances, reducing energy loss. Understanding this voltage is crucial for ensuring compatibility with electrical devices and safety in home wiring.
