verkkovirtakäyttöisiä

Verkkovirtakäyttöisiä refers to devices or appliances that operate by drawing power directly from the mains electricity supply, also known as AC power. This is in contrast to battery-powered or other portable energy sources. In Finnish, "verkkovirta" translates to mains electricity, and "käyttöisiä" means powered or operated. Therefore, "verkkovirtakäyttöisiä" literally means "mains electricity powered".

These devices are commonly found in homes, offices, and industrial settings where a continuous and reliable power source is available. Examples include refrigerators, televisions, computers, lamps, and power tools. They typically require a plug to connect to a wall socket, which provides the alternating current necessary for their operation. The voltage and frequency of the mains electricity vary by region, so devices are often designed for specific electrical standards. Safety features like insulation and grounding are crucial for verkkovirtakäyttöisiä appliances to prevent electrical shock. The efficiency and power consumption of these devices are important considerations for both economic and environmental reasons.
