Assignment:
An operational amplifier (Op-Amp) circuit is built to measure the temperature of an exothermic process in a lab. The circuit uses a thermistor (Resistance Temperature Detector) to monitor the target temperature and a voltmeter to measure the output voltage of the Op-Amp ciruit. Since the thermistor is a passive device, it requires and external battery to provide useful input, as shown in the ciruit diagram in attachment. The relationship between the resistance and temperature in the thermistor is relatively linear over a Temperature (T) range of 0deg Celsius and 200deg Celsius and is defined by Rt = 100 + 0.005*T. What will the Voltmeter read if the temperature of the reaction is 150deg Celsius? What are the potential sources of error in theis circuit and what might be done to improve any error that exists?
