What length of wire is required to create a resistor

Reference no: EM13979594

You are building your own resistor out of a common heating element material, Nichrome (ρ = 1x10^-6 Ω. m at 20^o C,a = 0.4x10^-3K^-1). You have a length of thin Nichrome wire (cylindrical) with a diameter of 0.1 mm.

a) What length of wire is required to create a 10 Ω resistor at room temperature?

b) What length of wire is required to create a 10 Ω resistor at 600 ^oC?
