Resistance calc

Thanks for the hands up.
Still curious to know is where you got 24.35 from? Or was it just a guess?

As far as I can see the value of 30.20 mohm/m was somehow divided by 1.24 which is the R1+R2. 30.20/1.24 = 24.35.

this calculation is a mistake.

This was made very clear by BAS, on his very own expressive way...

Albert...SPOT ON...on BAS as well.

This was a reply to Nijinski001 , Sorry about that, it might be that I fail into winding-up exercise....

I realised my decimal point error after posting. Even an incompetent like me wouldn't dream of putting 41,000 mtrs of cable in a house.

Still a decimal point error - the figure was 41000 km, not m....

This is beginning to look like a vendetta. It isn't, but you might like to make sure you know where your coat is....

Shouldn't make a difference when it comes to doing calculations. If it does, you ought perhaps to reconsider whether you should be DIYing electrical work....

I don't think you can use a "difference in units of measure" to explain away a completely barmy calculation of 30.2 ÷ 1.24.

I am impressed!, where do you find the time to find where this number came from...

Didn't actually take me any time.

If you look back, you'll see that my first answer was "IHNFI".

Later, I suddenly thought "Ah - hang on - is it 30.2 ÷ 1.24?":-

Continuity testing on 1.5mm T/E. A reading of 1.24 MOhm ...My tables (9A OSG) say 1.5/1.0 T/E is 30.2 mOhm/metre...

And lo, it was...

Heh hey... genius!!!
We can all put our coats back. Your powers never cease to amaze me BAS. I preferred the first response though (IHNFI) It showed a greater degree of humanoid falability.

And imagin how good you could be if you would not drink...
