arh, the coefficient is a percentage of the original resistance at 0°C
So to find the actual resistance increase per degree, I need to find out what 0.004% of .250 is
To do that I have to times my original resistance of .250 x the coefficient of 0.004 = 0.001Ω
this means that an...
hi, thanks for the welcome :)
The question I have is:
A long thin aluminium wire has a resistance of 0.250Ω at 0°C. Given that the temperature coefficient of resistivity at 0°C for aluminium is 4x10-3/0°C find the resistance of the wire at 200°C
Ive simply transported my values into...
Hi
I was wondering if anyone could help. My teacher isn't very good at explaining things and he's given us a question without going through the reasoning behind the equation.
