    length of circuit calculation - head scratching stuff!

    Hi all, How do I work out the length of a circuit? I have these figures R1+R2 = 0.40 The circuit is wired in 2.5mm/1.5mm T&E I take it I need to know the resistance of the T&E (where do I find this?) Could someone give me the formula or point me in the right direction Thank you.
