Figure P34

a. The given values of the resistances and the voltage ν1 are R1 = 5, R2 = 100, R3 = 200, R4 = 150, R5 = 250 k Ω, and ν1 = 100 V. (Note that 1 k Ω = 1000Ω.) 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 ν2.

b. Suppose we want to investigate how the resistance R3 limits the allowable range for ν2. Obtain a plot of the allowable limit on ν2 as a function of R3 for 150 ≤ R3 ≤ 250 k Ω.
