An RTD forms one arm of a Wheatstone bridge as shown in the figure. The RTD is used to measure a temperature with the bridge is operated in a balanced mode. The RTD has a resistance of 250 at a temperature of 0°C and a thermal coefficient of resistance a=0.003925C-1. The value of the variable resistance R, must be set to 41.485 Q to balance the bridge circuit. Determine the temperature measured by the RTD where R2=R3=100N
