First up is Direct Current, or DC. Picture a steady, reliable river flowing in one direction—that’s DC voltage. It’s the calm, consistent friend who always shows up exactly as planned.
Your phone, your remote control, and that tiny LED nightlight? They all run on DC. Batteries are the ultimate DC champions—they push electrons in a single, smooth stream.
Think of it like a straight line on a graph: flat, predictable, and a little bit Zen. If electricity were a marathon, DC would be the runner who keeps a perfect pace from start to finish.
