A336 m length of copper wire at 23c has aradius of 019 mm

1) A 33.6 m length of copper wire at 23?C has aradius of 0.19 mm . The resistivity of copperis 1.7 × 10?8 ? m. If a potential of 4 V is applied across the length of the wire, determine the current in the wire. Answer in units of A.

2) The temperature coe?cient for copper is 0.0039 (?C)?1 If the wire is heated to 32?C while the 4 V potential di?erence is maintained, what is theresulting current in the wire?Answer in units of A
