A sensor converts position from 0 to 2.0 m into a 4- to 20-m A current. An error detector such as that shown in Figure is used with R = 100 Ω,V0 = 5.0 V Rsp = 1 kΩ pot.
a. If the set point is 0.85 m, what is Vsp?
b. If Vsp = 1.5 V, what is the range of error voltage as position varies from 0 to 2.0 m?
