Answer:

The Temprature of wire determines the fusing current. Resistance of wire per unit is

R=p/πr²

where r is the resistance of wire per unit lenght, radius= r and p= redistivity

l²=πr³T^0/(Kp)

where T0is fusing Temprature. everything besides l amd r are constant so

l²is proportional. to r³
