I know there must be a difference, and reason why some wires have a solid strand behind the rubber, or some have several strands. can someone explain to me how it works and the differences in wire. m trying to get my head into electricity. resources would be good too.
Stranded or solid are the same in so far as performance. The stranded is used where flexibility is needed. solid wire is prone to breaking when repeatedly flexed. Solid wire is a bit cheaper, and easier to work with where you need the wire to stay in a particular shape. .
it just depends on your application, take for example your house has either solid 12 gauge or 14 gauge copper wire. solid copper has less resistance and can handle more amperage compared to say a stranded 12 or 14 gauge wire. you wouldnt wire your vehicle with solid wire would you? i mean theres no point, you dont need the amperage and the resistance of the wire is negligent here due to that fact there is not any long distances in your vehicle, plus it would be a pain to wire a vehicle with solid copper wire. in AC voltage they sometimes use square rectangular wire due to the fact that ac voltage travels on the outside of wire, rather than threw the entire middle, so a square wire offers more surface area.
you ask a fairly broad question first, the larger the wire, the more current it can handle as far as stranded wire, it flexes more during use and vibration and heating, etc. the solid wire is the smallest size and most accurate diameter if that is important such as high frequency
