What is the RCA wire?

RCA wire, or RCA cable, is a type of electrical cable commonly used to transmit audio and video signals. It features a single connector at each end, typically color-coded in red and white for audio channels and yellow for video. RCA cables are widely used in home entertainment systems, connecting devices like DVD players, gaming consoles, and televisions. Despite the rise of digital connections, RCA cables remain popular for their simplicity and ease of use.
