A 2.0mm length of a wire is made by welding the end of a 120-cm-long silver wire to the end of an 80-cm-long copper wire. Each piece of wire is .60mm in diameter. The wire is at room temperature. A potencial difgerence of 5.0 V is maintened between the ends of the 2.0-m composite wire.
a) What is the current in the copper section?
b) What is the current in the silver section ?
c) What is the magnitude of E in the copper ?
d) what is the magnitude of E in the silver ?
e) what is the potential difference between the ends of the silver section of wire ?
