Question

How does the electric current travel so
fast?
bulb​

Answer 1

How does the bulb in a circuit light up so fast? ... These in turn push the electrons in the wire forward (the “push” travels at the speed of light in the conducting wire, not the electrons) and the electrons *already in the wire* are what heats the filament to light the bulb.

Answer 2

Explanation:

these in turn push the electrons in the wire forward and the electrons already in the wire
