Any fraction that you like.
There are three different speeds here.The average speed of electrons - whether there is a current or not - is a significant fraction of the speed of light. That speed depends on the temperature. (The average VELOCITY of course is zero if there is no current, since as many electrons will go in one direction as in another.) The drift velocity (the average velocity) of the electrons is a small fraction of a millimeter per second. The exact value depends on the current, the cross section, and the material. The speed at which a signal can propagate in copper is about 2/3 of the speed of light in a vacuum - so, about 200,000 km/second. It is this speed that makes your light react quickly when you activate a switch.
speed of light I think well it sounds right:)
The speed of light in water is less than the speed of light in space. Only light can travel at the speed of light.
70.71% of c. That's about 131,721 miles per second.
The speed of light is about 880 thousand timesfaster than the speed of sound.
Time = 150Gm/c/n= 500secsxn where n is the fraction of the speed of light. If youb travel at 1/1000 of the speed of light then 500kseconds.
No. Just to travel AT the speed of light would require more energy than the entire universe contains. So all objects move at some fraction of light speed, never 1 nor greater.
Yes, typically about 2/3 of the speed of light in a vacuum - that is, about 200,000 km/sec. Note that the drift speed of the electrons is only a fraction of a millimeter per second, and the random speed of electrons is faster, but still much slower than the speed of the CURRENT.Yes, typically about 2/3 of the speed of light in a vacuum - that is, about 200,000 km/sec.

To go one light year in one year, you would have to be moving at the speed of light. No spacecraft can travel at the speed of light, if our theories about physics are even near to being correct. And no chemical-fuel rocket will ever approach even a fraction of one percent of light speed; THAT is certain, even if nothing else is.
Is what the speed of light or light speed.ANSWER300,000 km/s

In light speed.
