The cylindrical rod with a diameter d=1 mm is made from copper (29 65Cu). The density of the copper is 8900 kg/m3. Find the average drifting velocity of electrons in the rood, if the current in 1 A flows through the rod
5 Number of electrons Copper consists of atoms that each have 29 electrons and mass 1.06 x 10-25 kg. Copper has a density of 8.69 kg/m3 mo. Assume that the copper is electrically neutral. b) Suppose that electrons are removed from the copper so that it has a net charge of 5.0 x 10-9 C (this is a typical number for capacitors in electronic circuits). Determine the number of electrons that have been removed. c) What fraction of the total...
A 0.68-mm-diameter copper wire carries a tiny current of 2.4 μA . The molar mass of copper is 63.5 g/mole and its density is 8900 kg/m3. NA=6.02×1023. Estimate the electron drift velocity. Assume one free electron per atom.
