Resistance Of Cable

[kerching]

I thought it was 7 litres.......just shows how little i know..........see present wife for details

 

[Technician]

Reg;  421.1.5....flammable liquids. :Salute

Yes Technician the word litres is there.

I confess I did not search for litres, just litre, I expected the search to throw up the longer word.

I have now searched for litre, liter, Litre, Liter, litres, Litres, liters & Liters.

The only entries I could find are those in 421.1.5 with regard to flammable liquids.

So, anyone any ideas where the water volume thing comes from please?

I can't recall it at all, nor can I find it.

anyone have to hand the resistance of 1.00mm copper cable?

for some reason I have 2.14/100m in my head,

I have a table somewhere but for the life of me I cant find it,

If you ever get stuck again you could always work it out by calculation

(Resistance of copper X length ) / cable diameter

Resistivity of copper been 17.5x10-9

Length in meters

Diameter in meters (x10-6) if its in mm

Simple formula and resistivity of copper is what VAT used to be(then x10-9). I can never remember Ali of anything else is though.

Thats good to know, how long is my cable then?

Thats why I wanted to know the resistance, to see if the readings tied in with estimated length.
