SystemTheory said:This reference treats the transmission line as a superconductor for analysis, and yields results similar to the concept expressed by xantox (note k is the dielectric):

The speed of an electric signal refers to how fast an electric current can travel through a medium. It is typically measured in meters per second (m/s) or feet per second (ft/s).
The speed of an electric signal is determined by the properties of the medium it is traveling through, such as the type of material, its temperature, and its density. It is also influenced by external factors, such as the presence of obstacles or interference.
No, the speed of an electric signal is not constant. It can vary depending on the medium it is traveling through and other external factors. In a vacuum, the speed of an electric signal is constant and equal to the speed of light (299,792,458 m/s).
In most cases, the speed of an electric signal is slower than the speed of light. However, in certain materials with high conductivity, such as copper, the speed of an electric signal can approach the speed of light.
Yes, the speed of an electric signal can be increased by using materials with higher conductivity, reducing the distance the signal needs to travel, and minimizing external factors that can slow it down. However, it cannot exceed the speed of light in a vacuum.
