How Does a ‘Circuit Board’ Make Electronics Work?

A circuit board is like a map for electricity. It helps tiny electric messages travel from one part of an electronic device to another, making everything work together. Imagine it as the roads in a city, without them, cars (or electrons) can’t move around.

Circuit boards are covered with tiny paths made of metal. When you press a button on your phone or turn on a lamp, electricity follows these paths and lights up the screen or turns on the bulb. Without a circuit board, your devices would be like puzzle pieces, they wouldn’t know where to go.
