A 400-m long, 0.15 mm radius copper wire is coated with a thin insulating material. An engineer decides to use it for designing a temperature sensor for the range of -10°C to 20°C. A 1.5-V battery is used to bias the sensor. • Determine the resistance of the sensor and corresponding current at the two extremes of the sensor. ● • Determine the maximum power that the sensor will dissipate. Assume that the conductivity of copper is 5.8.107 S/m at 20°C and its temperature coefficient is 0.0039 Q/(°C).
