Aluminum wires were used in the past (until, due to their thermal expansion properties, it was found that they caused a lot of house fires). If a wire of copper, with a resistivity of 1.72 X 10-8 Ωm, was to be replaced with a wire of aluminum, resistivity of 2.65 X 10-8 Ωm, then how many times thicker would the aluminum wire have to be to offer the same resistance as a copper wire?

Now let's consider the resistance of speaker wire. Suppose you're hooking up a pair of stereo speakers, You happen to have on hand some 20-m-Jong pieces of 16 gauge copper wire (diameter 1.3 mm); you use them to connect the speakers to the amplifier. These wires are longer than needed, but you just coil up the excess length instead of cutting them. What is the resistance of one of these wires? To improve the performance of the system, you purchase...
