Aluminum, copper, gold, and nichrome wires of equal lengths of 1.0 10-1 meter and equal cross-sectional areas of 2.5 10-6 meter2 are at 20.0°C. Which wire has the greatest electrical resistance?
An electron moving in a wire collides repeatedly with atoms and travels an average distance between collisions called the mean free path. If the mean free path is less in some metals, what can you say about the resistance of these metals? For a given conductor, what can be done to lengthen the mean free path?
A 1.70 m cylindrical rod of diameter 0.550 cm is connected to a
power supply that maintains a constant potential difference of
12.0 V across its ends, while an ammeter measures the current
through it. You observe that at room temperature (20.0°C) the
ammeter reads 18.3 A, while at 92.0°C it reads 17.2 A. You
can ignore any thermal expansion of the rod.
