Cables in parallel formula

[brucelee]

hi mate
2.3 x 25 x 2 divide by 1000= 0.115ohm

Thanks for that but I think the way you have done it is if the cables where in series. Because there in parallel you have do: 1 divided by answer then 1 divided by total answer. Or so I was told when working with resistors. There was no mention of temp in the question so I guess they dont need it. Its on a past 2391 paper and I just wanted to know if I was working it out ok.

Cheers for the replys guys

Hi Jay you are correct i have worked it out for a series circuit sorry mate
I have looked into it and should have done it the way you said lol thanks for pointing my error learn something new every day mate cheers
