COAXIAL CABLE VS TWISTED PAIR: Understanding the Differences in Communication.

[@Tru2112]

incredible, thanks for going out and doing this extra research I wouldn't have thought to do really helped my understanding of the differences

[@TelecomTraining]

Glad it helped!

Can i use twis pair for speaker? which one better?

[@TelecomTraining]

Yes you can use either twisted pair or coaxial for speaker. Neither is ideal. If I had to pick one it would be twisted pair. Coaxial cable is good as well but more expensive to be used for just speaker wire.

Why wouldn't you change the shape of the copper wire? Make it like a relatively flat band so that it has more surface area per volume of copper material?

[@TelecomTraining]

Thanks for the question. Changing the shape of the wire from round to square won't solve the issue where high frequencies find high resistance down the middle of copper wire, and is forced to travel along the outer edge. This is called the skin effect.

🤔Why Coaxia cable must be 75 ohms !! why?

[@TelecomTraining]

Coaxial cable may have a different impedance depending on the cable. Like RG 6 75 ohms and RG8 50. The impedance of the cable should match the equipment it is connected too in order to have maximum power transfer.
