1. Find the voltages for each node using the equation for Long Run.

SUM {[(L n x (0.0045)) + (N t x (0.005))] x I n } <= 4.65V

Device 1 [(18 x (0.021)) + (1 x (0.005))] x 1.0 = 0.383V

Device 2 [(36 x (0.021))+ (2 x (0.005))] x 0.5 = 0.383V

Device 3 [(43 x (0.021)) + (3 x (0.005))] x 0.4 = 0.367V

Device 4 [(95 x (0.021)) + (4 x (0.005))] x 0.3 = 0.604V

2. Add each Devices voltage together to find the total voltage.

0.383V + 0.383V + 0.367V + 0.604V = 1.737V

Results

Since the total voltage does not exceed 4.65V, the system will operate properly.
