(a) A 35.1-m length of copper wire at 20.0°C has a radius of 0.23 mm. If a potential difference of 7.0 V is applied across the length of the wire, determine the current in the wire. (Use the values in this table.)

(b) If the wire is heated to 38.0°C while the 7.0-V potential difference is maintained, what is the resulting current in the wire?
