To learn to apply and combine the concepts of current, current density, and microscopic Ohm's law. An aluminum "12 gauge" wire has a diameter d of 0.205 centimeters. The resistivity p of aluminum is 2.75 x 10-8 ohm-meters. The electric field in the wire changes with time as E(t) = 0.0004f – 0.0001t + 0.0004 newtons per coulomb, where time is measured in seconds. Find the charge Q passing through a cross-section of the conductor between time O seconds and time 5 seconds.
