A cylindrical copper conductor with temperature coefficient 4.3x10^-3 K^-1 at room temperature (20 degrees C) has
radius 3.0 cm. The magnitude of the electric inside the conductor obeys the relation (6.0 V/m^2)r and points in the same
direction that the current travels. If you decrease the temperature to 10 degrees C, what is the current flowing through
the conductor?
