The given values of the resistances and the voltage v, are r = 5,
r2 = 100, r3 = 200, r4 = 150, r5 = 250 k12, and v, = 100 v.
(note that 1 k12 = 1000 12.) suppose that each resistance is rated to
carry a current of no more than 1 ma (= 0.001 a). determine the
allowable range of positive values for the voltage v2.
b. suppose we want to investigate how the resistance rz limits the
allowable range for v2. obtain a plot of the allowable limit on v2 as a
function of r3 for 150 s r3 s 250 kn.
38. many applications require us to know the temperature distribution in an
object. for example, this information is important for controlling the ma-
