While batteries store energy for the long haul, are the sprinters of the electronic world.

Every wire, every trace on a circuit board, is also a component.

They act as either an amplifier (turning a small signal into a big one) or a switch (turning a circuit on or off).

Together, these components take raw electrical potential and refine it into useful work, allowing us to light our homes, calculate complex equations, and connect with people across the globe. Understanding them transforms technology from "magic" into a logical, understandable system.
