Answer :
The speed at which electrons move through a wire is slow, while the speed at which the electric field propagates is much faster and determined by the wire's properties and frequency.
Electrons move through a wire in response to an applied electric field. In a battery-driven automotive circuit, the speed at which electrons move through a wire depends on the strength of the electric field and the resistance of the wire.
In general, electrons move through a wire at a very slow pace, typically on the order of millimeters per second. However, the electric field that drives the electrons through the wire travels much faster, at nearly the speed of light. This is because the electric field is not carried by the electrons themselves but rather by electromagnetic waves that propagate through the wire.
These waves can travel at speeds of up to 299,792,458 meters per second in a vacuum, although their speed can be slower in a wire due to the presence of the wire's material. In practice, the speed at which the electric field propagates through a wire is determined by the wire's electrical properties and the frequency of the wave.
