Can anyone help me on this one please....

How do i work this out ?????

The resistance of the cpc of a 15m , 1.25mm2 flexible lead ??????

im a bit stumped with this ...... many thanks in advance .... cheers ....

 
Using on site guide pg 166 Table 9a you could say resistance value for 1.25mm would be 15.1mohm/metre so (15.1 x 15) / 1000 = 0.23ohms.

Or measure using r2 method and low ohms meter
