ive been doing an experiment to do with fusing factors and unfortunately i didnt read

my experiment coursework sheet properly and have only recorded the current going

through a wire at a certain voltage. the results have then been used to work out the resistance,

i was wondering whether there was an equation to work out the fusing

factor with only the voltage, current, resistance and length

for example,

3cm length constantan wire

0.2v across the wire

reads an average of 3.01Amps

the resistance is therefore 0.07

i have read an old question that is exactly what i am doing but i am still rather confused.

anyone know anything about this?
