Do not use all things in the world to make something up and running properly mate 😇, it's not a fucken magical show. Just do a plan with the available resources on the table, then start apply using science not a fucken magical show. Choose wisely 🧠. There is NO 1 magical solution which fits all world problems.

Be aware of wire resistance techniques. It can be the distance between SERVERS on ground. KISS as much as you can.
The resistance of a wire is directly proportional to its length and inversely proportional to its cross-sectional area. Resistance also depends on the material of the conductor. The resistance of a conductor, or circuit element, generally increases with increasing temperature.
