Consider a copper wire with a diameter of 1.87 mm.
(a) What is the drift speed of the electrons in the copper wire when a current of 16.0 A flows through it? Assume that each copper atom contributes one free electron to the metal. The density of copper is 8.92 g/cm3. (b) How does this drift speed compare to the random rms speed of an electron at 20.0C? To make this comparison, determine the random rms speed of an electron at 20.0C using the ideal gas model and find the ratio of the two speeds.
