(a) Using the data in Table 12.1, compute the resistance of
a copper wire 1 mm (0.039 in.) in diameter
and 3 m (118 in.) long.
(b) What would be the current flow if the potential drop across
the ends of the wire is 0.02 V?
(c) What is the current density?
d) What is the magnitude of the electric field across the ends
of the wire?
