[grandfortune]

HI all,

can someone tell me what the R1&R2 reading on 100mtrs of 2.5mm would be

and has anyone got a table for working it out, been years since doing it but why do i remember 0.07 in my head, remember someone telliing me to think of james bond but cant seem to think why.

i assume there is a table somewhere in the big green book, but not getting my hands on it until the weekend

Cheers
Grand

im gonna go out on a limb here and speculate that 100m of 2.5/1.5 could be in the region of ooh , say 1.9 ohms ?

just saying
;-)

If the OP can manage to post the question on an internet forum, couldn't he have just looked the answer up on the interweb? :smilielol5:
