Answer :
Electrons move slowly, while electric field propagates nearly at the speed of light in a wire of a battery-driven automotive circuit.
Electrons in a battery-driven auto circuit travel at a generally sluggish speed, ordinarily on the request for millimeters each second. This is on the grounds that the electrons move in an irregular and flighty way through the wire, slamming into the molecules of the wire as they move.
The real speed of the electrons differs relying upon the sort of wire utilized, the voltage applied, and different variables. Nonetheless, it's vital to take note of that the electrical energy itself is moved immediately, as the electromagnetic field engenders through the wire at almost the speed of light.
The speed at which the electric field proliferates along a not entirely set in stone by the properties of the medium through which it ventures. In a vacuum, the speed of the electromagnetic field is equivalent to the speed of light, which is roughly 299,792,458 meters each second.
Notwithstanding, in a wire, the electric field ventures all the more leisurely, for the most part at around 50-the vast majority of the speed of light, contingent upon the properties of the wire.
The spread speed of the electric field is connected with the capacitance and inductance of the wire, as well as its obstruction and different variables. The electric field is answerable for moving energy from one finish of the wire to the next, permitting gadgets in the circuit to work.
