Physics · Chemical Effects of Electric Current

The table below lists the properties of three materials A, B, and C. Which of these materials would you use to make a fuse wire with a low current rating for a domestic electric circuit? Material A: Melting point = 1090 °C; Specific Resistance = 1.7 × 10-8 Ω m Material B: Melting point = 240 °C; Specific Resistance = 11.2 × 10-8 Ω m Material C: Melting point = 980 °C; Specific Resistance = 1.6 × 10-8 Ω m
