A RTD is used to measure the temperature of an oven. The RTD forms one arm of a Wheatstone bridge as shown below. E, = 10.23 volts. RTD properties: resistance of 123 N at a temperature of 0 °C, and a thermal coefficient of resistance of 0.003625 °C*. The value of the variable resistor R1 must be set to 162 Q to balance the bridge circuit. RTD RATD a. Determine the temperature of the RTD. b. Draw the circuit but replace the variable resistor R1 with a fixed resistor and replace the galvanometer with a voltmeter. Calculate the voltmeter's voltage.
