A copper wire in a typical residential building has a cross-sectional area of 3.31 x 10-6 m2 has8.94 x 1028 electrons/m3. If it carries a current of 10.0 A, what is the drift speed of the electrons?

Explain what drift velocity is.
In a typical lightning bolt, a current of 2.5 x 104 A exists for 20 μs. How much charge is transferred in this event?
The current in a wire is 0.80 A. How long does it take 1.60 C to pass through a point in the wire?
