What is the velocity factor of a transmission line?
Pick an answer to check it.
Answer: D. The velocity of a wave in the transmission line divided by the velocity of light in a vacuum
Velocity factor is the speed of a wave in the line divided by the speed of light in a vacuum. It is always less than 1.
Tip: VF = line speed / light speed.
