The fuse makes a bridge circuit from the power supply to the circuit being powered. Occasionally it joins several powered objects. For instance, your horn, running lights, and brake lights could all be powered from just one fuse.

A fuse can only manage so much power before burning out to protect the items being powered in the circuit. Fuses work on the same principle as a surge protector. When a power surge runs through the fuse, it blows without allowing the excess power to melt your wiring or expensive electrical gadgets in your car that might not stand up to the load.

A fuse is simply a safety measure against a circuit overload. When the fuse blows it makes the circuit incomplete, protecting the rest of the circuit from the additional power load.
