Question

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 218.0? . What is the temperature on a spring day when the resistance is 215.0? ? Take the temperature coefficient of resistivity for carbon to be ? = ?5.00 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 218.0? . What is the temperature on a spring day when the resistance is 215.0? ? Take the temperature coefficient of resistivity for carbon to be ? = ?5.00

Explanation / Answer

answer is 31.5 oC.here temperature coefficient is negative since there is decrease in resistance temperature would be high
