Consider a copper wire with a diameter of 2.77 mm. (a) What is the drift speed of the electrons in the copper wire when a current of 16.0 A fows through it? Assume that each copper atom contributes one free electron to the metal. The density of copper is 8.92 g/cm. 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 random rms speed of an electron at 20.0°C using the ideal gas model and find the ratio of the two speeds. Vems
