Why are wires (auxiliary, HDMI) so thin? Wouldn’t thicker larger wires transmit a signal more easily?
In: Engineering
Each of the pins on an HDMI cable or similar actually has it’s own wire that runs to the equivalent pin on the other end.
Thicker wires main advantage is that they allow for a stronger signal that is less prone to noise. However, they are also more expensive in raw materials, and when in a cable with many wires, they get pretty bulky pretty fast. Instead, we use other techniques for reducing the noise on the wires, such as how they’re twisted in pairs in the cable, or the shielding that’s on and in between the wires.
