Fuse circuit

You can see the fuse in series with the lamp on the right. Since a fuse's job is to protect electronic circuitry, it will break open if the current going through it exceeds a certain level depending on what current the fuse is rated for. If its rated current value is exceeded, the conductive metal inside of it will break open, so that the current cannot go across to damage the circuitry, which in this case is a lamp.
