The impedance of the fuse can usually be ignored in the entire circuit. However, for the Naga -level fuse, the impedance will reach a few ohms, and the pressure drop in the low -voltage line will be more conspicuous, and it needs to be considered. Most fuses are composed of positive temperature ... Read More
