A 10 meter length of wire consists of 5.3 meter of copper followed by 4.7 meter of aluminum, both of diameters 1 millimeter. A voltage difference of 38 mV is located across the composite wire.
(a) Determine the total resistance of the wire?
(b) Determine the current flow through the wire?
(c) Determine the voltage across the aluminum part?
(d) Determine the voltage across the copper part?
