A potential difference of 1.98 V will be applied to a 26.3 mlength of 18-gauge copper wire (diameter = 0.0400 in.). Calculate(a) the current, (b) the magnitude of the current density, (c) themagnitude of the electric field within the wire, and (d) the rateat which thermal energy will appear in the wire.
