The Biggest Misconception About Electricity

Most of us picture electricity as tiny electrons streaming from a battery through a wire to power a device — like delivery trucks carrying energy to a destination. But that picture falls apart the moment you ask a simple question: if electrons have to travel all the way around a circuit, why does a lamp turn on almost instantly, even when the switch is far away? The real answer is stranger and far more interesting than the mental model most of us carry. Electrons do move inside a wire, but they're not racing from the power source to your lamp. Instead, the energy travels through electromagnetic fields surrounding the conductors — and understanding how that works changes the way you see every cable, switch, and socket in your life.
