Basic Material Resistance Examples

Sarz11 · Apr 16, 2014

I dont know how helpful people will find this or whether they care or already know and think its too basic or whatever but i learnt it an old knowledgeable boy (he knows who he is) said it took him back to his apprentice days so it definately cant be harmful to know and learn. The rho values for the materials arnt real there just for working out purposes and you will end up with a really low resistance. Its not hard really just if your starting out i guess and want a go

. I cant/(maybe wont until feel more confident) get involved with much at the minute but i am loving what i am doing

ps cant do the symbol on my phone for "to the power of minus" so il have to write it out.

Rho values:
Copper = 17.5 x 10 (to the power of minus 9)

Aluminium = 28.5 x 10 (to the power of minus 9)

Total Resistance of:

Copper conductor 90m in length and c.s.a of 4mm

Aluminium Conductor 82m in length c.s.a. of 16mm

Copper Conductor 120m in length and c.s.a of 2.5mm

Aluminium Conductor 25m in length and c.s.a of 35mm.

0.39 ohms

0.14 ohms

0.84 ohms

0.02 ohms

its a bit late so it may be wrong but doubt it haha, they are pretty easy saz i haven't posted up my working out as i don't want to ruin it for any one else, if you need any help with these let me know they are pretty easy to learn once you know the formula.
