Current in a wire is due to the flow of electrons in the wire. Although the drift speeds of electrons in the wire is small, yet an electrical bulb lights up as soon as the switch is on . Explain Why

=> Yo, Current in the wire is due to the flow of electrons in the wire / current.
=> But, Wait Wait Wait -:D
this doesn't mean that each electron will travel from one end to other end in a conductor to ignite the light.
=> There is mass of electrons present in wire /conductor , and the Electric Impulse /(Practically current ) produced by electrostatic repulsion in wire, travels at speed of light on that medium.
=> This speed of Impulse imparted along the conductor is speeded enough that Electric Bulb lights up as soon the switch is on.
