E9F02
Which of the following has the biggest effect on the velocity factor of a transmission line?
Pick an answer to check it.
Answer: C. The insulating dielectric material
The insulating dielectric between conductors mostly sets how fast waves travel in the line. Line length and conductor resistance do not change velocity factor.
Tip: Dielectric sets velocity factor.
