An AC outlet is a socket designed to provide alternating current (AC) electricity to power various devices and appliances. These outlets are commonly found in homes, offices, and public spaces, allowing users to plug in items like lamps, computers, and kitchen appliances. Typically, an AC outlet has two or three slots for prongs, depending on the electrical system in a given country. The standard voltage and frequency can vary, with many regions using 120 volts at 60 hertz or 230 volts at 50 hertz. Proper use of AC outlets ensures safety and efficiency in electrical consumption.
