A safety device that protects an electric circuit from becoming overloaded. Fuses contain a length of thin wire (usually of a metal alloy) that melts and breaks the circuit if too much current flows through it. They were traditionally used to protect electronic equipment and prevent fires, but have largely been replaced by circuit breakers.
A cord of readily combustible material that is lighted at one end to carry a flame along its length to detonate an explosive at the other end.
Verb
To melt something, such as metal or glass, by heating.
