Answer to Question #84174 in Electrical Engineering for Aaron
The density of copper is 3 3 8.93 10 / kg m . 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 mole and the molar mass of cupper is 63.55g.
