How many pins do RCA cables have?

RCA cables may vary depending on their intended use. For example, the most common type of RCA cable includes 3 pins on each end. These pins are divided into audio (2) and video (1). The two audio pins transmit the left and right stereo audio channels while the yellow marked pin carries the video signal. Other common configuration is to have separate cables for audio and video. In this case, the audio cable will be divided into two for the left and right audio while still being a single cable, and the yellow cable will carry the video feed.
