How signal is transmitted through only one wire (red) of simple RCA cable?
What is use and how works ground wire (black)?

That is probably because there was another ground to ground connection present.MarkWW said:Cable transmit signal(sound) without black wire, I tested it.
An RCA (Radio Corporation of America) cable transmits a signal through a series of electrical connections. The signal is carried through two separate wires, one for the left audio channel and one for the right audio channel. The signal is then amplified by the device it is connected to, such as a TV or audio receiver.
A RCA cable transmits an analog signal, meaning that it carries a continuous electrical signal that can vary in amplitude and frequency. This is different from a digital signal, which is made up of binary code (0s and 1s).
The maximum distance a RCA cable can effectively transmit a signal depends on various factors such as the quality of the cable, the strength of the signal, and any interference. In general, a RCA cable can transmit a signal up to 50 feet without any noticeable degradation in quality.
No, a RCA cable is not capable of transmitting high-definition signals. It was originally designed for analog audio signals and is not able to handle the higher bandwidth required for high-definition video. For high-definition signals, it is recommended to use an HDMI cable or other digital connection.
Some common issues that can affect the transmission of a RCA signal include loose connections, damaged cables, and interference from other electronic devices. It is important to ensure that the cable is securely connected and in good condition to ensure the best quality signal. Placing the cable away from other electronic devices can also help minimize interference.
