A fuse is a very thin wire Jordan 12 Retro For Sale , which either melts or vaporizes when too much current flows through it. The thin wire may be made of aluminum, tin-coated copper or nickel. The resulting open in the circuit stops current flow. In electronic equipment, most fuses are cylindrical glass or ceramic type with a metal cap at each end! The current rating also can be seen in one of the two metal end caps. There are two popular physical sizes: 1 ?
The purpose of a fuse is to open an electronic circuit when current flow exceeds a certain amount Jordan 13 Retro For Sale , determined by the rating of the fuse. Opening a circuit under high current conditions can save electronic components from damaged and prevents overheating, which could cause a fire.
