In question video I asked you what thing A and thing B is. Today’s answer (answer video) will provide you basic info but if you want even more info, check the Resources. Thing A: WIRE A wire is a single conductor that is tipically made of copper, aluminium or sometimes steel (steel is not for electrical use). Wire can be with or without the jacket/isolation which is colored for easyer use and non-conductive. We know solid and stranded conductor types where stranded conductor is more flexible handling less power and lower frequency than one solid conductor of the same cross-section diameter but both are comparable weight. Longer the conductor is, higher is the resistance and also has more power/signal loss. ...
