A copper wire has a diameter of 1.350 mm. What magnitude of current flows when the drift velocity is 3.09 mm/s? Take the density of copper to be 8.92 g/cm3. Give your answer in Amperes.
How to do these two problems 3. -1 points OSColPhys2016 20.1.WA.008 My Notes Consider a copper wire with a diameter of 2.51 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 m/s (b) How does this drift speed compare to the random rms speed of an electron...
