A typical wall socket designed for small appliances, such as hair dryers, is rated at how many volts?

The correct answer is that a typical wall socket designed for small appliances, including hair dryers, is rated at 110 volts. In many residential settings in the United States, wall outlets for general purposes are designed to operate at this voltage level, allowing various small appliances to function safely and effectively.

This voltage rating ensures that standard household devices can operate with adequate power without risking overload or damage. The use of 110 volts for everyday appliances is a longstanding standard, providing a balance between safety and efficiency in residential electrical installations.

In contrast, the other voltage ratings mentioned are generally used for different applications. For example, 220 and 240 volts are typically reserved for larger appliances that require more power, such as ovens, dryers, and HVAC systems. These devices need higher voltages to function efficiently, which is why they are not compatible with the typical 110-volt outlets intended for small appliances.
