Who Showed That Electricity Travels At The Speed Of Light? In free space the radiation travels at the “speed of light” but the radiation can also travel down two wires at the speed of light unless the two wires are surrounded a dielectric like plastic. A guy named Maxwell,a creative physicist,developed the theory and first

How Fast Does Voltage Travel Over Pcb Trace?

How Fast Does Voltage Travel Over Pcb Trace? Let’s calculate the propagation delay/time delay using trace length and vice-versa. Mathematically, time delay is tpd:1/v. Where v is the speed of the signal in a PCB transmission line. In vacuum/air, it’s equal to 85ps/in. What is the speed of signal approx? In circuit boards made of
