    Well I could tell you the relationship, but that would be no fun.

    What you need to do is get lots of different lengths of the same wire (material and crosssectional area) and measure the resistance.

    You could try it with something other than wire too, I bet you have access to some different length metal rods and things too, those are worth a try too.

    Once you have a data set, then you can move onto finding the relationship.

I checked the resistance of my 90 Honda DX injectors and came up with 1.1 and 8 ohms. Can anyone tell me what it should be? Seems odd that they are different. Thanks

Resistance [ 1 Answers ]

Hi! :) I'm doing a GCSE coursework and could you please give me a very detailed explanation of how resistance is caused in a wire (constantan wire) as its length is increased;why the resistance increases. Thank you so much :-*
