why semiconductor fuse used in drive ,not ordinary?
Answer Posted / tariq
Because semiconductors has negative resistance temperature
co-efficient. When current flows in it, its temperature
increases due to I^2*R losses but resistance decrease
accordingly. The decrease in resistance allows more current
to flow in it which produces more heat. It will melt
ultimately.
