A typical wall socket designed for small items like hair dryers supplies how many volts?

120 volts
110 volts
240 volts
80 volts

The correct answer is: 110 volts

The correct voltage for typical wall sockets designed for powering small appliances, such as hair dryers, is 120 volts. This standard is commonly used in North America. While it is true that 110 volts was historically the nominal voltage, the actual voltage supplied is usually at 120 volts due to various factors like load and regulation standards. It's important to recognize that appliances designed to be used with wall sockets are specifically engineered to operate within this voltage range, ensuring safety and efficiency. Appliances rated for 240 volts are generally used for larger devices, while 80 volts is not a standard voltage for household electrical systems. Therefore, the best understanding aligns the operational needs of small items with the commonly accepted voltage standards.
