# Answer to Question #84174 in Electrical Engineering for Aaron

Question #84174

The density of copper is 3 3 8.93 10 / kg mï‚´ . Calculate the number of free electrons per

cubic meter and hence their drift velocity when a current is flowing whose density is 21 / A cm . Take Avogadro’s number as 23 6.022 10 / atoms moleï‚´ and the molar mass of cupper is 63.55g.
