Hi Guys and Girls I have been given an investigation to do on "Fusing Factors of wires" I have looked at the effect that increasing the length of a wire has on the fusing current. I know that it doesnt effect it but i do not know why! I also have looked at diameter of the wire in relation to fusing current. I know that as you increase the diameter of the wire the fusing current increases but again do not know why! Does anyone have any explainations to these? Any views would be much appreciated!
