No. Three types of speed must be distinguished here:
1. The random movement of electrons is pretty fast, but still only a fraction of the speed of light. They will have this movement, whether there is a current or not.
2. The drift velocity is the average velocity of electrons when there is a current. This velocity is typically a fraction of a millimeter per second.
3. The velocity of the electric signal itself is typically about 2/3 the speed of light in a vacuum (that is, about 200,000 km/sec). What happens here is that energy is transferred from one electron to another. Imagine one electron bumping into another and pushing it forwards.
No, electric current is the flow of electrons through a conductor, but the individual electrons do not move at near the speed of light. Instead, the speed of electron movement in a conductor is typically much slower.
the wave front of electric current. the electrons themselves move much slower but they keep pushing electrons ahead of them on resulting in a wavefront that moves at almost the speed of light.
No, protons do not travel through an electric circuit at or near the speed of light. In a circuit, electrons are the charge carriers that move through the wires at speeds much slower than the speed of light. Protons typically remain within the nucleus of an atom and do not move freely in a circuit.
They don't. Nothing can exceed the speed of light. Electrons in a television travel much slower than the speed of light.
They can ONLY move slower than the speed of light.
Electrons are able to travel close to speed of light.
Because electricity is the movement and flow of electrons, which are matter. Since they are matter, they cannot reach the speed of light.AnswerBy the 'speed of electricity' you presumably mean the 'speed of charges through a conductor'? (Remember 'electricity' is not a quantity!). The answer is that they move through a conductor v-e-r-y slowly -for normal conductors, just a fraction of a millimetre per second!
A calculator can only operate as fast as the electrons that carry the current through its circuits. Electrons have mass, and mass can never travel at the speed of light; therefore, calculators do not operate at the speed of light.

In general, light propagates at c, the speed of light (that is, 299,792,458m/s), however when travelling through a medium such as an optical fibre, this will decrease, but will still travel at a constant speed dependent upon values such as the materials permittivity and permeability. Light travels easiest through insulating mediums, and cannot travel far through conductors.

In wires and other conductors, electrons travel very slowly. They drift along at molasses speeds, like 1 mm/sec. In vacuum tubes, electrons travel more quickly, around 1% of the speed of light. But the speed of the electrons isn't really important for circuits. What matters is the speed of electric field waves. These waves travel down the wire almost up to the speed of light, and they are responsible for the "instantaneous" effects we see from electricity. Think of a wave traveling across the surface of a slow-moving river, or the speed at which sound waves travel through slow-moving air. Waves can travel much faster than the medium that carries them.

The speed of electrons in the beam is typically close to the speed of light, which is about 186,282 miles per second.
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.

yes, of course.
