Explore the every step required to calculate the answer of the given problem-
Problem- An engineer needs a resistor with a zero overall temperature coefficient of resistance at 20o C. She designs a pair of circular cylinders, one of the carbon and one of Nichrome. The device must have an overall resistance of R1 + R2 = 10.0 Ω Independent of temperature and a uniform radius of r = 1.50 mm. Ignore thermal expansion of the cylinders and assume both are always at the same temperature.
Part 1- Can she meet the design goal with this method?
Part 2- If so; state what you can determine about the lengths of each segment. If not, explain.
You want help to evaluate the answer of the above problem.
