Hi all, I've been a long time reader of this forum but haven't signed up for whatever reason. So thanks for the wealth of information and solutions to my headaches. I'm trying to figure out a coefficient of temperature equation and I'm having a hard time with the manipulation for some reason. I know the formula is: a=alpha R2=R1[1+a(T2-T1)] However, the variable I'm solving for is T2. I'm given R1,T1,R2,Coefficient of metal @ 20 degrees Celsius. I'm a little ashamed because I know this isn't hard at all but its been a long time since I've been at this stuff. Thanks.
