A 15 meter length of wire consists of 6 meter of copper followed by 9 meter of aluminum, both of diameter 1.2 mm. A voltage difference of 95 mV is located across the composite wire. The resistivity of copper is 1.68 × 108 Ω•m and the resistivity of aluminum is 2.65×108 Ω•m.
a) Determine the total resistance of the two wires?
b) Determine what is the current through the wire?
c) Determine the voltage across the copper part?
d) Determine the voltage across the aluminum part?
