插座w什麼意思

插座（W）通常指的是電源插座，是用於連線電源線和電器的一種裝置。W是英文單詞「wall」的縮寫，意為牆壁上的插座。這種插座通常安裝在家庭、辦公室或其他建築的牆壁上，用於為各種電器設備提供電力，如燈具、電視、電腦、手機充電器等。

插座有不同的類型和標準， depending on the country or region. For example, in the United States, the most common type of wall socket is the 110-120 volt AC outlet, which has two vertical slots for the live and neutral wires, and a third round hole for the ground wire. In the United Kingdom and other countries that use the British standard, the wall socket is a three-pronged outlet with two flat slots for live and neutral and a vertical slot for the earth wire.

When referring to a wall socket, it's important to note the voltage and amperage rating to ensure that the appliance being plugged in is compatible with the power supply. Using the wrong type of plug or attempting to use an adapter for a different standard can be dangerous and may result in electrical damage or fire hazards.
