Halayen Fis ɗin

Aikin fuse yana faruwa ne ta hanyar narkewar narkewar narkewa. Fuse ɗin yana da wata siffa a bayyane, wato, sifar ampere-second. Ga narkewar, sifofin aikinsa na yanzu da lokacin aiki sune sifofin ampere-second na fuse ɗin, wanda kuma ake kira halayen jinkiri na lokaci mai juyawa, wato: lokacin da ƙarfin overload ya yi ƙanƙanta, lokacin fuse ɗin yana da tsawo; lokacin da ƙarfin overload ɗin ya yi girma, lokacin fuse ɗin ya yi gajere.

Domin fahimtar halayen ampere-second, za mu iya gani daga dokar Joule cewa a cikin da'irar jerin, ƙimar R na fiyu ba ta canzawa ba, kuma ƙimar calorific ɗin tana daidai da murabba'in halin yanzu I, kuma tana daidai da lokacin dumama T, wato: lokacin da halin yanzu Idan ya fi girma, lokacin da ake buƙata don narkewar ya busa ya fi guntu.
