Question

Consider a copper wire with a diameter of 1.27 mm. (a) What is the drift speed of the electrons in the copper wire when a current of 11.0 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 000642 m/s (b) How does this drift speed compare to the random rms speed of an electron at 20.0°C? To make this comparison, determine the randon rms speed of an electron at 20.0°C using the ideal gas model and find the ratio of the two speeds. .000000000; Yd Review the ideal gas model. How is the rms speed related to the temperature and mass?

Explanation / Answer

Vrms = sqrt ( 3RT/M)

M = 9.1 x 10^-31 kg

Vrms = 8.9614 x 10^16 m/s

ratio = Vrms/Vd = 1.4 x 10^20
