Congrats pennychew - would you care to share your prize winning answer ?

 

[GMES]

So we have another Trainee with a prize to donate, this keeps getting better Very generous of you mate thank you!!

 

[pennychew]

Congrats pennychew - would you care to share your prize winning answer ?

Ive just checked my sent PM's for the answer but ive deleted it, Doh!

looks like im going to have to work it out again while slightly tipsy!

 

[Simonslimline]

2.5 / 1.5 = 1.67.

So the answer is R1 x 1.67 gives the value for R2.

This is now my headache? There is more than one correct answer that is acceptable! Pennychew's answer was 0.98 Ohms btw.

Depending on which formula you use and the amount of decimal places you use, there are 4 different correct answers lol. I need to think about that next time!

Out of the 1468 saved PM's, yours is one of them! You used the same formula as Simon above btw.

 

[pennychew]

Right.... when the cpc (R2) is 1.5mm2 and the live conductor (R1) is 2.5mm2 then the CSA of R1 is 1.666667 times the CSA of the smaller cpc...

So the resistance in the smaller cable (cpc) should be 1.6666667 times higher than in the live conductor so 0.59 x 1.666667 = 0.98ohms

 

[pennychew]

2.5 / 1.5 = 1.67.

So the answer is R1 x 1.67 gives the value for R2.

Thats what i was trying to get at! took me 4 minutes longer though!

 

[newtothis]

2.5 / 1.5 = 1.67.
So the answer is R1 x 1.67 gives the value for R2.

Thanks for that.
Gawds honest truth, I thought it was a trick question, so didn't enter :dunce2:

You probably havent covered these formulas at college yet though mate, keep reading on here and asking questions and it will soon stick

 

[Paul.M]

Thanks for that.

No trick questions in here, just the odd question that will stick with you all throughout your life.

eg, 6mm line conductor with a 2.5mm cpc or a 10mm line conductor with a 4mm cpc, what is the ratio?
