Why is it important to unplug electric appliances when not in use?

• A. They continue to draw electricity even when they're not turned on
• B. They lose their charge only when on
• C. They become more powerful when unplugged
• D. They attract dust more when unplugged

Answer: (A)

This question is about standby power, sometimes called phantom load. Many electric devices keep a tiny amount of power flowing to them even when you’ve turned them off or aren’t actively using them. That happens because internal components like clocks, displays, memory, or wake-on-demand circuits stay powered so the device can wake quickly or remember settings. The importance of unplugging is that this small trickle adds up. Across many devices in a kitchen or home, it can waste energy and increase your electricity bill over time. It’s why you’ll often hear to unplug chargers or use a switched power strip to cut power to multiple devices at once when they’re not in use. Common cases you might think of include TVs with standby lights, digital kitchen appliances, and phone or tablet chargers. Unplugging or cutting power when not needed prevents that continuous draw. Dust buildup isn’t the main issue here, and the idea that devices become more powerful when unplugged isn’t accurate. The key idea is that they continue to draw electricity even when they’re not turned on.
