A copper wire of cross sectional area A=1.7 mm2 and Lenght L=1 m carries a current of I=6.4 A at the temperature of T1= 20 0C.

a) How many electrons pass through a cross section of the wire in each second?

b) What is the resistance of the wire?

c) What is the potential difference between the ends of the wire?

d) What is the resistance of the wire at the temperature of T2= 100 0C? (r=1.7x10-8 W.m, a=7x10-3 0C-1)
