2. Repeat Problem 1, but this time resistor R₁ is fixed and resistor R₂ is implemented using two terminals of a 10k pot so that R₂ is variable over the range 0 ≤ R₂ ≤ 10kſ. Find the largest value of the resistor R₁ that will allow the output voltage to vary over a range that includes at least 1.5V ≤ V₂ ≤ 5.0V. Show how you arrived at this value. Then, choose a resistor (or combination of resistors) from your parts kit that will get you as close as possible to (but no larger than) your calculated value for R₁.
