Measuring Temperature Using a Carbon Resistor ?

A carbon resistor is to be used as a thermometer. On a winter day when the temperature is 4.00 c , the resistance of the carbon resistor is 217.9 Omega . What is the temperature on a spring day when the resistance is 215.7Omega ?Take the temperature coefficient of resistivity for carbon to be alpha = −5.00×10−4C^{-1} .

R = R° ( 1 + α Δt)R = R° + R° α Δt(R - R°) / R° α = Δt(215.7 - 217.9) / 217.9 * -5 10^-4 = Δt2.2 / -0.10895 = ΔtΔt = 20.192temperature on a spring day = 4°C + 20.192 = 24.2 ° Chttp://hyperphysics.phy-astr.gsu.edu/hbase/electri...Goodbye... Show More
