Audio enthusiasts spend a lot of money on their stereos. When they connect loudspeakers to their amplifiers they commonly use 12-gauge (2.0525 mm diameter) copper wire. Some extreme audiophiles will use 18-gauge (1.0237 mm diameter) silver wire. The copper wire is $2.50 per meter, and the silver wire is $500. • Determine the resistances for a 1.00 meter length of each wire. • Which wire has the least resistance? If you had the money, could you justify the expense of the sliver wire? Explain!

Expert Solution
Step 1
Given data,
Diameter of copper wire = 2.0525 mm
Diameter of silver wire = 1.0237 mm
Resistivity of copper = 1.68x10-8 ohm-meter
Resistivity of silver = 1.59x10-8 ohm-meter
