A certain temperature sensor experience a change in electrical resistance with temperature according to the equation R=R0(1+a(T-T0)) Where the temperature coefficient a=0.00395/0c. This temperature sensor is connected in a wheatstone bridge as shown in figure 3 (a). Where the sensor occupies the R1 location, and R2 is calibrated variable resistance. The bridge is operated using the null method. The fixed resistance R3 and R4 are each equal to 500 ohms. If the temperature sensor has a resistance of 100 ohms at 00c. Determine the value of R2 that would balance the bridge at 00c.
