E.g. I have a DHT11 sensor which I would like to extend. At the moment I have only a short 10cm long data cable and it works fine, but what if I wanted it longer. Or if I wanted to power a 5v relay over a distance of say 5m My question is: If I know the resistance of the long wire, how can I compen…

Compensating for lead resistance.

No, you can only get 5V - but at real low current flow.
5/10,000,000 = .5uA.
