what is a fuse
In electronics and electrical engineering, a fuse (from the French fusee, FusÃ©e italian, fuso) spindle is a type of low resistance resistor that acts as a sacrificial device to provide overcurrent, protection of either the load or source. circuituses have the advantages of often being less costly and simpler than a circuit breaker for similar ratings. The blown fuse must be replaced with a new device which is less convenient than simply resetting a breaker and therefore likely to discourage people from ignoring faults.
