Determine the resistance limit of the switch by using the specification given (Hint: Use Ohm’s Law, i.e., R=V/I)

Scenario for Part 1:
A telecommunication company is tasked to design a subscriber loop that will follow the road map below to provide telephone services in a
subdivision. The initially designated service area interface (116 C. Lawis Extension) and the distribution point (San Luis, Antonio) are 3.7 km and
4.5 km, respectively, from the central office. One subscriber is 0.4 km from the distribution point (4.9 km from the central office).
