I have just started theCity & Guilds 2330 electrical installation on day release from work.
I am finding some of the maths a bit tricky.Can anyone out there explain to me how the answer to this maths question was reached
R= 17.5X10-9(ohms sign)mX100m
__________________________ =1.9ohms
1.5X10-6m2
the 9 and the 6 after the minus signs are written small in the text book i think they are multiplication factors.
Thankyou.
