The equations describing the circuit shown in Figure P37 are
a. The given values of the resistances and the voltage υ1 are R1 = 5. R2 = 100, R3 = 200, R4 = 150, R5 = 250 kΩ, and υ1 = 100V.
(Note that 1 kΩ = 1000 0.) 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 2.
b. Suppose we want to investigate how the resistance R3 limits the allowable range for υ2. Obtain a plot of the allowable limit on υ2 as a function of R3 150 ≤ R3 ≤ 250 for kΩ.
