[QUOTE="collinsmark, post: 5749379, member: 114325"] That looks correct to me! :smile: 'Just a heads-up though, 1) The symbol you used "∝" is, I think, the "proportional to" symbol. I believe you meant to use "α" alpha. 2) In your final equation, I[SUB]o[/SUB] = 1/6 I[SUB]o[/SUB] [1+α(T-T[SUB]o[/SUB])], you've used two "I[SUB]o[/SUB]"s. I'm pretty sure one of them should be an "I". 3) You haven't specified your value for Tungsten's temperature coefficient of resistance. In the future, you should specify such things in either the problem statement section or the relevant equations section. Otherwise it looks good to me. :smile: [/QUOTE]
