Here is a good one if you go into your wholesalers and purchese 100 meters of 2.5 twin- earth what should be the r1+r2 reading

 

[mechelec]

2.5 with 1.5 cpc 19.51milli ohms per metre gives 0.1951 ohms

 

[Sintra]

2.5 with 1.5 cpc 19.51milli ohms per metre gives 0.1951 ohms

0.1951 ohms is the value for 10 M

100M would be 1.951 ohms.
