In a copper wire that has a diameter of (1.63 mathrm{~mm}), the drift velocity is (7.08 times

Question:

In a copper wire that has a diameter of \(1.63 \mathrm{~mm}\), the drift velocity is \(7.08 \times 10^{-4} \mathrm{~m} / \mathrm{s}\). If we assume one free electron per copper atom, what are 

\((a)\) the current in the wire and 

\((b)\) the current density?

(c) This wire connects a light bulb, power source, and switch in a circuit, and the distance between the switch and bulb is \(3.00 \mathrm{~m}\). How long does it take for an electron initially at the switch to reach the bulb?
