The resulting open in the circuit stops current flow
The fault was a short circuit or other problem that caused a lot of current to flow very quickly. Unfortunately, a high probability exists that if a fuse blew, something in the circuit it was protecting shorted out. But if the inside of the glass fuse is discolored, and there is no trace of the fuse element (the center connector), you know that the center connector was destroyed quickly and violently, using a lot of heat.
The resulting open in the circuit stops current flow. The blown fuse can easily be replaced by a new one, after the overload has been eliminated when come into replacement. Connect the probes to both end of the fuse. A good fuse should showed continuity or read 0 .Jestine Yong is a electronic repairer and writer.Types of Fuses There is two basic types of fuses: fast acting and slow blow. A blown fuse can tell you something about your service problem. Fuses Glass Teapots Manufacturers available with current ratings from 1/500 Ampere to hundreds of amperes.Is some cases a fuse will open up fast enough when there is a surge so that other components aren’t damaged. Often the glass case of the fuse appears clear, and you can still see the broken pieces of the fuse element. In this case, a replacement fuse blows right away. When you buy replacement fuses, get several ? you can easily use all of them while you’re troubleshooting an elusive problem. Opening a circuit under high current conditions can save electronic components from damaged and prevents overheating, which could cause a fire.
The 1 X ? – inch size is used in many automobiles.A fuse is a very thin wire, which either melts or vaporizes when too much current flows through it. If this is the case, replacing the fuse with one of the same type and rating restores operation. Use only the same current and voltage ratings as the original. You may check the fuse while it still in circuit. There are two popular physical sizes: 1 ? ? X ? – inch and 5X20mm.Testing Fuses Turn the power off and remove the fuse from the circuit to check with a multimeter set to the lowest ohms range.
