5. Thermistors are temperature-measuring devices based on the principle that the thermistor material exhibits a change in electrical resistance with a change in temperature. By measuring the resistance of the thermistor material, one can then determine the temperature. For a 10K3A Betatherm thermistor, the relationship between the resistance R of the thermistor and the temperature is given by 1 T ; = 1.129241 × 10¯³ +2.341077 × 10¯4 In R + 8.775468 × 10¯³ (ln R)³ where T is in Kelvin and R is in ohms. Use the bisection method of finding roots of equations to approximate the resistance R at a temperature of 19°C accurate to ±0.03. (Note that the temperature in Kelvin is equal to the temperature in degrees Celsius plus 273.15.)
