A carbon resistor is to be used as a thermometer. On a winter day when the temperature is 4.00(Degree C.), the resistance of the carbon resistor is 218.0(Greek "w') . What is the temperature on a spring day when the resistance is 215.8(Greek "W")?
Take the temperature coefficient of resistivity for carbon to be (alpha) = −5.00×10−4C^-1
I am not so sure how should i start... what equation should i apply in here? .
