My second attempt with Inform
Before I retired, I was a professional electrical engineer. I have done a lot of electrical site work, which included street/path lighting, outlets for street tree systems (holiday lights), ball field lighting, etc. Good engineering practice requires that the voltage drops through the system must be evaluated because the National Electrical Code mandates that the total voltage drop in total through the system must not exceed 3% of the supply voltage. For example, on a 240V circuit, the voltage at the end of the circuit may not be less than 232.8V.
I have boring Excel spreadsheets to facilitate the calculation, but I saw an oppo to try something new.
The program calculates the voltage drop in the circuit between each pair of nodes as well as a total voltage drop from source to end. Those of you who know Ohm's Law will get it. Feel free to play with it.

It's not the having, it's the doing.
