WHATS FASTER THAN LIGHT FULL

Wiring to carry electricity normally includes 2 conductors (and sometimes a 3rd ground conductor). Remember that an electric circuit requires a complete loop, unlike a laser. And also the capacitance to ground and/or to the other conductor. Not just the resistance of the conductors, but the inductance. Hope this helps.Īlso, does the speed of the electricity depend on the voltage applied or the resistance of the conductor?

WHATS FASTER THAN LIGHT FULL

If you use a high speed coaxial cable (like a 3GHz satellite TV cable) instead of a wire, the delay would be much shorter (80-90% of the speed of light to the full voltage). It is not really a delay per se, because the initial low level signal would get there almost with the speed of light, but its amplitude would only gradually increase and reach the full voltage with a substantial delay that would depend on the cable and circuit impedance (mostly on the cable inductance). While at the input the voltage would increase very fast, at the output it would increase gradually, as if with a delay. In your example, the very moment of switching on represents a high frequency front that will be attenuated. However, different frequencies have different attenuation. The speed does not directly depend on the voltage or resistance. Good cables achieve 80% of the speed of light excellent cables achieve 90%. The cable geometry and the insulation both reduce the speed. The speed also depends on the cable construction. So it is normally lower, but not too much lower than the speed of light in the vacuum. The speed of electricity is conceptually the speed of the electromagnetic signal in the wire, which is somewhat similar to the concept of the speed of light in a transparent medium.
