Suppose the current in a 1.50 mm diameter copper wire is 2.5

Suppose the current in a 1.50 mm diameter copper wire is 2.5 A is used to light a bulb, and the number density of the free electrons in the metal of the wire is 3.001025 m a) Find the drift velocity of the electrons. b) How long would it take an electron with this drift velocity to travel 4.50 m from the switch to the bulb? c) Explain, then, why the bulb lights up immediately when the switch allows the current to begin flowing.
