How does a fuse work
We all know that when an electric current flows through a conductor, the conductor will get hot because of its resistance. From this formula, it is easy to see how a fuse works in a simple way.
How does a fuse work? Once the material of which the fuse is made and its shape is determined, its resistance, R, is relatively certain and as the current flows through it, it will heat up, and as time goes by, so does the amount of heat generated. The size of the current and resistance determines the rate at which heat is generated, and the construction of the fuse and the condition in which it is mounted determines the rate at which heat is dissipated, and if the rate of heat generation is less than the rate of heat dissipation, the fuse will not blow. If the rate of heat generation is equal to the rate of heat dissipation, the fuse will not blow for a long period of time. If the rate of heat generation is greater than the rate of heat dissipation, the amount of heat generated will increase. Because of its specific heat and mass, the increase in heat is reflected in the increase in temperature, and when the temperature rises above the melting point of the fuse, the fuse will blow. This is how a fuse works. How does a fuse work, In this principle, it should be understood that the physical properties of all materials must be carefully studied and their geometrical dimensions must be consistent during the design and manufacture of the fuse? This is because these factors play an important role in the proper functioning of the fuse. Likewise, you must install the fuse properly when you use it
