question_answer 5)

At room temperature (27.0°C) the resistance of a heating element is 100. What is the temperature of the element if the resistance is found to be 117 , given that the temperatures coefficient of the material of the resistor is 1.70 × 10?4 °C?1.  

Answer:

Using, R2 = R1 (1 + T), we get                                    i.e.                                   i.e.                                  T2 = 1000 + T1 = 1000 + 27                 = 1027 °C.
