How many Ohms separate RGB wires?

The correct answer is 75 Ohms, which is significant in the context of video signal transmission. RGB (Red, Green, Blue) wiring systems, often used in video applications, typically operate with a characteristic impedance of 75 Ohms. This impedance allows for optimal signal integrity and minimal reflection when transmitting video signals.

Using cables with an impedance that matches this standard helps in preserving the quality of the signal by minimizing transmission loss and distortion. Deviations from the 75 Ohm specification can lead to signal degradation or interference, which is particularly critical in high-frequency applications found in video systems.

The other impedance values listed—50 Ohms, 100 Ohms, and 150 Ohms—are commonly associated with different types of cables used for distinct purposes, such as networking or specific audio applications, but they do not apply to RGB wiring. Understanding these standards is essential for professionals in the mobile electronics field to ensure proper installation and performance of video systems.
