1. A sensor resistance varies from 520 to 2500 2. This is used for R, in the divider along with R, 500 ft and V, 10.0 V. Find (a) the range of the di- = vider voltage. V, and (b) the range of power dissipation by the sensor. V 2. A sensor with a nominal resistance of 50 R, R, 100, V 10.0 V. and R, 100- resolve 0.1-2 changes of the sensor resistance. a. At what value of R, will the bridge null? is used in a bridge with potentiometer. It is necessary to b. What voltage resolution must the null detector possess? 3. A current balance bridge, has resistances of R, - R = 1k, R. = 590 12. R, = 10 11, and V = 10.0 V. a. Find the value of R, that nulls the bridge with no current. b. Find the value of R, that balances the bridge with a current of 0.25 mA.
