This document describes an experiment to determine the temperature coefficient of resistance for platinum using a Carey Froster bridge and platinum resistance thermometer. The experiment involves measuring the resistance of the platinum wire at room temperature (R1) and at 100 degrees Celsius (R2). These resistance measurements are used to calculate the temperature coefficient of resistance for platinum by comparing the change in resistance over the temperature change. The experiment is performed in three parts: 1) determining the resistance per unit length of the bridge wire, 2) measuring R1 and R2, and 3) calculating the temperature coefficient and comparing to the standard value of 37.0 x 10^-4 per degree Celsius.
